This vulnerability can be chained with CVE-2026-105133. CISA added CVE-2026-105134, CVE-2026-105133 to the Known Exploited Vulnerabilities catalog on 2026-10-14 based on evidence of active exploitation.
Arista patched an actively exploited critical SQL injection flaw (CVE-2026-114625, CVSS 9.9) in on-prem VeloCloud Orchestrator that lets any authenticated user gain operator privileges and masquerade as the local 'superuser operator'. Hosted VCO is already patched; on-prem admins need to upgrade.
2026-10-22: Arista disclosed CVE-2026-114625, an actively exploited SQL injection in on-prem VeloCloud Orchestrator, with fixes in 5.2.3.18, 6.1.3.10 and 6.4.2.12. Hosted VCO is already patched. Arista advised restricting the VCO web interface to admin networks, blocking 74.82.197.86 and 38.54.50.151, and preserving logs before remediating if compromise is suspected. (source)
Multiple Atlassian products (Bitbucket Data Center ,Confluence Data Center, Jira Service Management Data Center, Jira Software Data Center, Bamboo Data Center, Crowd Data Center, Crucible and Fisheye) contain a files or directories accessible to external parties vulnerability which could allow an unauthenticated attacker to access specific files within the web application root directory in affected versions. Added to CISA KEV on 2026-10-15.
China-nexus actor ARMORY CASTLE (ex-UNC5221) exploited CVE-2026-102764, a critical unauthenticated file-operations flaw in BeyondTrust Remote Support, as a zero-day from late August 2026. BeyondTrust issued BT26-05-RS; SaaS was auto-patched by Oct 9; CISA added the CVE to KEV on Oct 16. Self-hosted appliances need the patch plus forensics — patching alone does not clear existing footholds (SAWFLY / BARECLAW).

BT26-05-RS patch for self-hosted RS 24.3.1-26.2.3 (older versions must upgrade first); SaaS auto-patched Oct 9
Kaspersky GReAT found a new UEFI bootkit, BlackX, used in early 2026 against diplomatic organizations in Tajikistan, Uzbekistan and Turkmenistan and attributed with medium confidence to China-linked APT41. It is a copycat of BlackLotus and exploits Baton Drop (CVE-2022-21894) to install its own Machine Owner Keys, load arbitrary EFI files and inject a kernel driver that blinds security software. The targeted machines were fully patched: Microsoft's fix only revokes the vulnerable "Windows Production PCA 2011" signing certificate after an admin manually sets a registry flag under HKLM\SYSTEM\CurrentControlSet\Control\Secureboot and runs the Secure-Boot-Update task, and Microsoft's planned automatic enforcement phase has not shipped. The certificate expired on Oct 19, 2026, but that does not stop vulnerable boot binaries from loading unless it is in the DBX blocklist. Attackers need admin rights or physical access first, so this is a persistence tool, not an initial access vector. Windows admins should apply Microsoft's Secure Boot revocation steps manually.
Fixed in
Protection requires manually enabling Microsoft's Secure Boot revocation (registry flag plus the Secure-Boot-Update scheduled task); see Microsoft's Boot Manager revocation guide, Microsoft's automatic enforcement phase has not shipped yet

Report URI and iVerify found criminals using 660+ re-registered expired analytics and ad-tag domains (DeadTag), hacked PrestaShop stores and a malicious Instagram ad to silently serve the Coruna (iOS 13 to 17.2.1) and P7 DarkSword (iOS 18.4 to 18.7) exploit kits. Opening an affected page on a vulnerable iPhone is enough; the spyware steals keychain passwords, crypto wallet data and device info. Updated iPhones are protected, so update iOS (or turn on Lockdown Mode if you can't).

FoxIO published research (Oct 20 2026) showing that missing or late decoded-header limits in QPACK let a tiny HTTP/3 HEADERS frame expand into huge server memory use (up to ~4000× on Bun). Seven of ten implementations tested were vulnerable; quic-go, Cloudflare quiche, lsquic and Wireshark are patched, while Bun, aioquic/mitmproxy and h3 remained unpatched at publication.
ISC disclosed a remotely exploitable memory-corruption bug in BIND 9's named on Oct 21. An attacker who captures a GSS-TSIG signed UDP message (the Kerberos signing used for Active Directory-style dynamic DNS updates) can replay it while the negotiated key is still valid and, combined with crafted queries to a zone they control, may get remote code execution, or at least crash named. CVSS 8.1 (High). No workaround. Affects BIND 9.11.0 through 9.18.50, 9.20.0 through 9.20.29 and 9.21.0 through 9.21.26. Fixed in 9.20.30 and 9.21.27; ISC lists no 9.18 fix. ISC knows of no active exploitation. Debian trixie has a fixed package; Debian bookworm and Ubuntu are still waiting.

Volexity observed threat actor UTA0576 chaining an Ivanti Connect Secure authentication-bypass / RCE zero-day (CVE-2026-104935) with additional flaws from about Oct 1–3 2026 to get unauthenticated root on fully patched appliances, re-exploiting in memory without planting webshells. Ivanti patched CVE-2026-104935 on Oct 13; CISA added it to KEV. One privilege-escalation piece of the chain was still being fixed at disclosure.
A flaw in Keycloak's reset-credentials flow (keycloak-services) lets an unauthenticated attacker force a password reset for any user without clicking the emailed verification link, then set new credentials and take over the account. Red Hat rates it CVSS 9.1. Fixes shipped in August (26.4.15, 26.6.6, 26.7.2); on Oct 21 a full proof-of-concept with check and takeover modes was published on Exploit-DB, so unpatched Keycloak instances should be upgraded now.
2026-10-21: Exploit-DB publishes EDB-52699 "Keycloak 26.7.2 - Unauthenticated Account Takeover" by Abel Maldonado (Orevim): a PoC with a safe --check mode and a --set-password takeover mode, tested on Keycloak 26.6.2. (source)

On Oct 21, Trend Micro's Zero Day Initiative sent several unpatched Linux kernel vulnerability reports to security@kernel.org but Cc'd the public linux-kernel and subsystem lists, so full technical details (code paths, KASAN traces) are now public before fixes ship. The worst are two ksmbd (in-kernel SMB server) remote code execution bugs that ZDI scores CVSS 9.0: an SMB Direct integer underflow (needs an RDMA device and a writable share) and a protocol-dispatch race (needs a guest share). Also leaked: an skb_zerocopy local privilege escalation (ZDI-CAN-33367, CVSS 7.8), a vmwgfx out-of-bounds write LPE, and an nvmet info leak. ZDI-CAN-33367 now has a working public exploit: CloudLinux confirmed it gives any local user root on AlmaLinux 8, 9 and 10, Debian 12 and 13, and Ubuntu 24.04 and 26.04 where unprivileged user namespaces are allowed, and setting user.max_user_namespaces to 0 closes that path. No CVEs yet and no fixed mainline or stable release; the skb_zerocopy fix is posted for review but not merged, KernelCare has a livepatch only for CloudLinux/AlmaLinux 10, the ksmbd race fix sits in the ksmbd maintainer tree, and an SMB Direct fix is in a branch aimed at Linux 7.5. No exploitation in the wild reported. Only machines running ksmbd are exposed to the RCEs.

On Oct 14 2026 Vercel shipped Next.js 16.4.1 and 15.5.28 with two critical unauthenticated remote code execution fixes held back from the September release: CVE-2026-96889 / GHSA-2464-fhr4-w9xw, a use-after-free in librsvg (via sharp) reachable through the Image Optimization API when SVGs are processed on glibc-based Linux, and GHSA-673q-mjm6-r5xr, RCE in App Router apps with Cache Components when a `use cache` function returns multiple typed arrays. A high-severity Server Actions DoS (GHSA-p3m5-59mp-jv5r) is fixed too. GitHub added the SVG advisory to its global database on Oct 22. No known exploitation.

2026-10-22: GitHub publishes GHSA-2464-fhr4-w9xw to the global Advisory Database (critical), so Dependabot and npm audit start flagging affected next versions. (source)
2026-10-14: Vercel releases Next.js 16.4.1 and 15.5.28 as an out-of-band security update: two critical unauthenticated RCEs (SVG Image Optimization, `use cache` typed arrays) and a high-severity Server Actions DoS. No workaround for the `use cache` bug; upgrade even if you don't use those features. (source)

Node2Shell (CVE-2026-111497, also written Node 2 Shell) is a Brotli decoder out-of-bounds write in Node.js that can let an attacker run code when an app decompresses attacker-controlled Brotli data: Express 5 / body-parser 2.x request bodies sent with Content-Encoding: br, Brotli responses read by fetch(), or node:zlib on untrusted input. OpenAI Codex Security (Khai Tran and Sylvie Mayer) reported it; Node.js fixed it on Oct 21 2026 in 26.12.1, 24.22.1 and 22.23.4, alongside nine other CVEs (TLS hostname/IP bypasses, DNS NUL truncation) and a CA store refresh for the eMudhra incident. On Oct 22 Imperva Red Team, which coined the name Node2Shell, ran code on the official Node.js 24.22.0 image. NVD lists CVSS 4.0 9.2 (critical); Node.js rates it High. End-of-life lines (Node.js 20, 23, 25 and older) get no fix: upgrade to 26.12.1, 24.22.1 or 22.23.4. Bun is fixed in 1.4.4.
2026-10-22: End-of-life Node.js 20, 23 and 25 get no fix. Anyone on them has to move to 26.12.1, 24.22.1 or 22.23.4. Bun shipped the fix in 1.4.4. (source)
2026-10-22: NVD record for CVE-2026-111497 updated: the Google CNA scores it CVSS 9.2 (critical) and places the root bug in Google Brotli 1.0.3 through 1.2.0 (c/dec/decode.c), so other software bundling Brotli needs updating too. (source)
2026-10-22: Imperva Red Team (Ron Masas) names the bug Node2Shell and runs code on the official Node.js 24.22.0 image (Linux arm64) through fetch() and Express 5 / body-parser 2.x. It took several attempts; 24.22.1 rejected the same input. (source)
A command-injection flaw in the OpenCode AI coding agent let a malicious or later-hijacked remote MCP server run PowerShell commands on a developer's Windows or WSL machine when they started the MCP OAuth sign-in. The server-supplied authorization endpoint was passed unescaped to an old version of the open package. Anomaly fixed it in 1.18.33 on Sep 28 without a CVE or advisory, so scanners won't flag 1.0.137 through 1.18.32. macOS and Linux are not affected. Pillar Security found it and rates it 9.8; no in-the-wild exploitation reported.

Palo Alto Networks PAN-OS contains a code injection vulnerability that could allow an authenticated attacker with network access to execute arbitrary code with root privileges on the firewall. Added to CISA KEV on 2026-10-14.
Two critical remote-code-execution flaws in PHP core (CVE-2026-109618 and CVE-2026-109619, aka “PHP2Shell”) were disclosed early after an embargo leak. Both score CVSS 9.2 and can let an unauthenticated attacker run code on servers serving PHP web requests, especially Apache mod_php. Patches shipped Oct 21 2026 (appliance vendors such as QNAP are still preparing fixes); exploitation attempts were observed before and after the patch, and watchTowr / AWS report active scanning.
2026-10-23: The PHP Foundation advises keeping session.upload_progress.enabled=0 until the next PHP release to block a further, unlikely RCE vector (CVE-2026-115560).

Sophos retracts an earlier report of a successful compromise; no vendor has confirmed one so far. (source)
Four Plex Media Server flaws (CVE-2026-96652/96654/96655/96656), together called Plex2Shell, chain to unauthenticated admin-token theft and code execution. Researcher Zach Main published details Oct 16 and a PoC shortly after; exploitation of internet-facing servers (cryptominers + residential proxies) began by Oct 17. Fixed in 1.43.3.10861 (released earlier in August); CISA added the chain to KEV with a federal deadline of Oct 23.
Paulos Yibelo / pwn.ai found a Critical Linux networking flaw (CVE-2026-99999, CVSS 9.3) during Vercel’s $1M Sandbox challenge. Guest-controlled checksum metadata can rewrite an IPv4 header after validation, enabling host-memory disclosure and, in lab conditions, guest-to-host code execution on KVM/Firecracker. Upstream fix merged Oct 2026; host kernels need patch + reboot. Affects multi-tenant VPS / sandbox providers more than end-user desktops.

Ruby released 4.0.9, 3.4.12 and 3.3.13 on Oct 23 2026 to fix bugs in its Onigmo regular-expression engine (a double free and integer overflows) that GitLab turned into remote code execution on its servers, tracked by GitLab as CVE-2026-89078, CVE-2026-93577, CVE-2026-97229 and CVE-2026-110264. Any Ruby app that compiles a regex from an attacker-controlled string (Regexp.new, Regexp.union, Regexp.compile or /#{input}/) is exposed; Regexp.timeout and pattern-length limits do not protect. Apps that only use their own hard-coded regexes are not affected. Ruby 3.2 and older are end-of-life and get no fix.
2026-10-23: Ruby releases 4.0.9, 3.4.12 and 3.3.13 with the upstream fixes: a double free when parsing fails after an alternation (#13332), an integer overflow in the compiled pattern size (#19020) and an overflow of internal IDs in patterns with many repeats (#16801). Ruby requested no CVEs of its own and says to track GitLab's IDs in scanners. Credit: Johan Carlsson (joaxcar) via GitLab's bug bounty; GitLab reported and coordinated. (source)
2026-10-23: Ruby 3.3 is in security maintenance and gets the Regexp fixes as an exception. 3.3.13 also updates the default resolv gem to 0.3.2, fixing CVE-2026-80212 and CVE-2026-80213. (source)
2026-10-21: GitLab 19.5.1 and backports fix CVE-2026-110264 (CVSS 10.0, unauthenticated RCE from an integer overflow when compiling a crafted regex), affecting every CE/EE version from 7.0. (source)
Siemens Software Center contains an uncontrolled search path element vulnerability that could allow an authenticated local attacker to place a specially crafted DLL in a directory that the application searches, leading to arbitrary code execution with the privileges of the affected application. Added to CISA KEV on 2026-10-20.
V12 disclosed 25 flaws in the x402 agent-payment SDKs, three rated critical: the default client had no spending limit (a hostile API could ask for an agent's whole token balance), the TypeScript Solana facilitator accepted token approvals as payments, and the SIWx login helper signed messages for other websites. All three were fixed in the August 18 releases, but no advisory was published, so npm audit and PyPI don't warn. Update @x402/fetch, @x402/axios, @x402/extensions and @x402/svm to 2.23.0 or later.
2026-10-23: The Hacker News found the foundation published no security advisory for the three flaws, so npm audit and PyPI report nothing for the last vulnerable releases. Patched clients now cap each payment at $1 and allow only recognized USD stablecoins unless the app sets its own spend controls. (source)
2026-10-22: V12 published 25 x402 findings with three critical ones detailed: no default spend limit, Solana ApproveChecked accepted as TransferChecked in the TypeScript facilitator (a complete payment bypass in local tests), and SIWx signing relayed login messages for other domains. The x402 Foundation had fixed all three in the August 18 releases. (source)
Zammad GmbH Zammad contains an improper privilege management vulnerability that can allow the local zammad user to escalate privileges to root. This vulnerability can be chained with CVE-2026-102489. CISA added CVE-2026-102490, CVE-2026-102489 to the Known Exploited Vulnerabilities catalog on 2026-10-02 based on evidence of active exploitation.
A bug in RingRTC, the open-source library behind Signal's voice and video calls, lets the other party on a call flood the call's state-machine event queue so a local hang-up gets stuck behind the backlog, and audio (possibly video) keeps flowing to them after the victim thinks the call ended. Affects every Signal client (Android, iOS, Desktop) embedding RingRTC before 2.72.0. Fixed in RingRTC 2.72.0 (released Sep 4 2026, disclosed Oct 20); a conceptual PoC is public, no known exploitation.
2026-10-22: No known exploitation; CISA has not added it to KEV and NVD lists it as awaiting analysis. (source)
2026-10-22: SecurityWeek: the hang-up was queued behind peer events with no rate limit or priority; the fix makes call termination bypass the queue. Users should update Signal and check the call indicator after hanging up. (source)
2026-10-22: Closed on pwn.watch: the fix shipped Sep 4 (RingRTC 2.72.0), there is still no known exploitation and no new developments, so this is now a patch-and-move-on item. Make sure Signal is updated on every device. (source)
Storybook disclosed CVE-2026-114125 on Oct 21 2026: the dev server's preview iframe could be embedded by any website and accepted postMessage events from any origin. A malicious site open in the same browser could, with some user interaction, make a running `storybook dev` server change story files in your project, and a changed file could then be executed by a local runtime with your privileges. Storybook 8, 9, 10 and 11 alpha are affected (including @storybook/addon-mcp and @storybook/addon-vitest). Fixed versions shipped Oct 12; Storybook says it is not aware of exploitation. Built (static) Storybooks are not affected.
2026-10-22: Closed on pwn.watch: fixes are out for every affected major and there is no known exploitation. Upgrade Storybook (and the Visual Tests addon to 5.5.1+ if you use it) and don't run an old dev server meanwhile. (source)
2026-10-21: Advisory GHSA-f2ph-cmg5-wxc8 / CVE-2026-114125 published. Storybook says it is not aware of exploitation in the wild; upgrade before running storybook dev again. (source)
2026-10-12: Patched releases 8.6.19, 9.1.21, 10.6.2 and 11.0.0-alpha.6 ship. They block cross-host iframe embedding of the dev server, reject postMessage from unknown origins and rework the highlight event (new feature flags can re-enable the old behaviour). (source)
nginx published multiple medium/major advisories fixed in 1.31.7+ and 1.30.6+, including HTTP/3 request-body injection (CVE-2026-95101), TLS session-ticket forgery (CVE-2026-97629), AIO use-after-free (CVE-2026-97205), and buffer overflows in alias/rewrite and map/regex paths.
