Track 1 — active exploitation

Being exploited right now

Between the monthly briefs: vulnerabilities with a CVE that are on the CISA KEV catalog or carry evidence of exploitation in the wild. This is the short list — the things whose patch window has already closed.

Data as of 09 November 2026, 18:31 UTC · Source brief 2026-11-09 Cadence checked weekdays — the date above moves only when a card changes, so an old date means no card has changed since, not that nobody looked

Patch priority — 186 under active exploitation

Ranked in from the brief. Every entry here has a CVE and either a CISA KEV listing or independent evidence of exploitation.

CVE-2026-102895CVSS 9.8Exploited

GPUStack (open-source GPU cluster manager for model serving) before 2.2.0 — exploitation observed against 2.1.1

Authentication bypass by trusted loopback source (CWE-287/290/346): a same-host reverse-proxy peer or a forged X-GPUStack-Real-IP: 127.0.0.1 header makes the request the built-in administrator; persistent admin API keys and code execution on workers via POST /v2/inference-backends/from-yaml

SignalWire FreeSWITCH 1.11.2 and earlier (mod_sofia / mod_verto chat api proto; chat on by default unless enable-chat=false)

Command injection via the SIP MESSAGE 'api' chat proto (CWE-77/78/749) — remote execution of FreeSWITCH API commands by any one registered account on the profile, or by anyone where a passwordless directory user (stock 'default') remains

CVE-2026-123158CVSS 8.1Exploited

OpenBSD OpenSSH Portable before 10.6p2 on Linux built with musl libc and PAM disabled — in practice Alpine Linux openssh-server (sshhole.com also names OpenWrt, Buildroot, Yocto and many container images built on musl without PAM; the CVE record calls Alpine 'An example') (all releases 3.16–3.24 and edge), or openssh-server-pam with UsePAM no, with PasswordAuthentication yes; glibc distributions, PAM builds (UsePAM yes), OpenBSD and Dropbear are not affected

Authentication bypass (CWE-394, unexpected status code or return value): musl crypt() returns '*' for keys over 256 bytes and sshd accepted it as a match for an account whose shadow field is '*'; needs one other account with a $5$ / $6$ hash on the host; unauthenticated, network

CISA deadline2026-07-24
Patched inNO CONFIRMED FIX: the GitHub-reviewed advisory GHSA-g22f (not a maintainer advisory) lists no patched version and ZDI published it as a 0-day after no vendor response; KEV cites v1.9.0, whose release notes never mention it. v1.10.1 is the first release whose notes say validate_code no longer executes code (the CVE-2026-9198 fix), so 1.10.1 or later is the defensible floor (our inference, not a vendor statement). Do not expose Langflow to untrusted networks. Workaround: ZDI: 'the only salient mitigation strategy is to restrict interaction with the product'. Langflow v1.9.0 added LANGFLOW_ALLOW_CUSTOM_COMPONENTS=false (PR #11893) to block execution of non-template component code. Not stated as a mitigation for this CVE. After patching: ZDI: code executes in the context of root, so treat the host and all stored credentials/flows as compromised (inferred).

Patched inNO CONFIRMED FIX: the CVE record says versions before 21.1050 are affected, but Samsung's bulletin (SVP-AUG-2024) names no fixed version, and Arctic Wolf reports 21.1050 is still exploitable. CVE-2025-4632, the bypass of this fix (same Samsung bulletin page), is fixed in versions before 21.1052 per its CVE record, so treat 21.1052 as the floor. Our recommendation: run the latest MagicINFO 9 Server release and keep the server off the internet. Workaround: None stated by Samsung. Arctic Wolf (third party): ensure MagicINFO Server is not internet-facing. After patching: Not stated by Samsung. Arctic Wolf: arbitrary file write enables RCE via uploaded JSP files.

Unauthenticated SQL injection in the MOVEit Transfer web application → database access, then web shell deployment and mass exfiltration

Exploitationyes — CISA KEV with knownRansomwareCampaignUse: Known. Exploited as a zero-day from late May 2023 by Clop; EPSS remains near 1.0 three years later, indicating sustained exploitation attempts against surviving unpatched instances
KEV added2023-06-02
CISA deadline2023-06-23
Patched inPatched MOVEit Transfer releases from 2023-05-31 onward; no interim workaround was published. Secondary and non-optional: any instance that ran unpatched past May 2023 should be handled as a possible prior compromise — rotate credentials and conduct a forensic review rather than assuming the upgrade is sufficient

CVE-2026-120422CVSS 8.9Exploited

Sogou (Tencent) Sogou Input Method / Sogou Pinyin for Windows before 16.10 (SGTool.exe configuration retrieval over HTTP)

Cleartext-HTTP configuration retrieval (SGTool.exe) → DNS-hijacked response instructs arbitrary-path file download → DLL side-loading of the DarkVigil implant; nation-state surveillance campaign

Exploitationyes — ESET Research, from its own telemetry: 'Beginning on July 1st, 2026, we observed' victims of SlippyNunchucks' DNS-hijack delivery through this flaw (HK, Thailand, Japan, Vietnam, Oman, Sri Lanka). Vendor (Tencent) makes no public exploitation statement found; not on KEV v2026.11.03
Patched inSogou Input Method 16.10 (Tencent; released 2026-10-29 or 2026-10-30 — ESET's post gives both dates) — migrates the affected HTTP requests to HTTPS and enables certificate pinning. Disclosure: reported 2026-09-11, acknowledged 2026-09-21, CVE-2026-120422 issued 2026-11-02 (ESET CNA)

Vendor watch — advisory-tracked, not exploited

These are not under active exploitation and are not part of the patch-priority list above. They are severe vendor advisories we corroborated and are tracking until fixes land everywhere, including some the public CVE system does not carry yet (where live NVD lookups return NOT FOUND, scores are vendor/CNA-only). Anything here that reaches the CISA KEV catalog or is observed exploited moves into the list above.

CVE-2026-98432CVSS 9.8Advisory only

Linux kernel 4.4 and later (IPv4 TCP; reached via any listening TCP service; demonstrated against MPTCP listeners) — all major distributions

Use-after-free (race) of IPv4 request-socket options in tcp_v4_syn_recv_sock() / ip_options_build() — unauthenticated remote kernel memory disclosure and corruption. A remote-root exploit (MPTCP-listener path) was demonstrated privately by the reporter; no public exploit, no exploitation reported

Ubuntu: NOT yet fixed on any release (26.10/26.04/24.04/22.04 'work in progress'; 20.04/18.04/16.04 'Vulnerable'; 2026-11-03).

Stop-gaps that reduce but do not remove risk: an nftables rule dropping inbound TCP with IPv4 options, applied on the host (covers the host and containers whose traffic it routes; same-host container-to-container traffic may bypass it; breaks traffic that relies on IP options); disabling MPTCP closes only the demonstrated path (Go 1.24+ listeners enable MPTCP by default; GODEBUG=multipathtcp=0)
