CVE-2026-84869CVSS 9.9Exploited
ConnectWise ScreenConnect — client prior to 26.6.5. ScreenConnect servers are explicitly NOT impacted per the vendor bulletin
Improper privilege management / missing authorization → files transferred and executed through an active remote session without Host confirmation
Exploitationyes per CISA KEV (added 2026-09-11, deadline 2026-09-14, known ransomware use: Unknown). ⚠️ The vendor bulletin does NOT claim in-the-wild exploitation — it rates the issue Priority 1 (High) using risk-of-targeting language. Vendor/catalog disagreement recorded, not resolved
KEV added2026-09-11
CISA deadline2026-09-14
Patched inScreenConnect 26.6.5 (vendor bulletin 2026-09-08, read 2026-09-11). Interim mitigation where the update cannot be applied at once: deselect the TransferFiles permission for all user roles under Administration > Security > Roles — the vendor states this 'may reduce exposure until the update is applied', i.e. mitigation, not a fix
Incorrect authorization — token validation checks the signature/issuer but not the token's scope, allowing privilege escalation
Exploitationyes per CISA KEV (added 2026-09-11, federal deadline 2026-09-25, known ransomware use: Unknown). JFrog's advisory does not itself state in-the-wild exploitation

Patched inJFrog Artifactory 7.133.11 — from JFrog's security advisories page, read 2026-09-11 (advisory published and updated 2026-07-27). No workaround is offered; upgrade is the remediation. Supply-chain follow-up: review artifact pushes and token issuance during the exposure window, since a patch does not un-publish a poisoned artifact
Improper authentication — an internal anonymous-user token can be returned to an unauthenticated caller while anonymous access is disabled
Exploitationyes per CISA KEV (added 2026-09-11, federal deadline 2026-09-25, known ransomware use: Unknown). JFrog's advisory does not itself state in-the-wild exploitation

Patched inPer-train fixes from JFrog's security advisories page, read 2026-09-11 — 7.111.20 · 7.117.27 · 7.125.19 · 7.133.28 · 7.146.8 (advisory published 2026-08-12, updated 2026-08-13). No workaround. ⚠️ Different fix line from CVE-2026-42016 (7.133.11) in the same 7.133 train — verify the exact build against BOTH advisories, and rotate tokens that could have been disclosed while the instance was vulnerable
MikroTik RouterOS — fixed in 6.49.21 (Long-term), 7.23.4 (Long-term), 7.24.2 (Stable), 7.25 beta 3; earlier builds in those trains affected. Vendor states 'Most configurations are not at risk' without enumerating which
Improper neutralization of argument delimiters in a command — a username beginning with a prohibited character alters the trusted RouterOS policy mask via the SSH login helper, leading to privilege escalation
Exploitationyes — MikroTik's own advisory (2026-09-03) states the vulnerabilities are actively exploited and withholds technical detail to allow time to update. CISA KEV added 2026-09-10, federal deadline 2026-09-13, known ransomware use: Unknown

Patched inRouterOS 6.49.21 (Long-term), 7.23.4 (Long-term), 7.24.2 (Stable), 7.25 beta 3 — from MikroTik's advisory read 2026-09-11. VENDOR MITIGATION where an update cannot be applied at once: ensure SSH is not open to any untrusted network; preferably expose no management ports and reach the device over a VPN such as WireGuard. Exploitation requires an unauthenticated SSH session to the login helper, so removing that reachability removes the attack path
MikroTik RouterOS — fixed in 6.49.21 (Long-term), 7.23.4 (Long-term), 7.24.2 (Stable), 7.25 beta 3; earlier builds in those trains affected
Missing authentication for a critical function — a 'related' btest connection is accepted before the primary session authenticates; with random-data=false the sender leaks an uninitialized kernel packet-buffer tail, and an unchecked inverted packet-size interval causes unsigned integer underflow, oversized fragmented output and a kernel restart
Exploitationyes — MikroTik's advisory (2026-09-03) states the September vulnerabilities are actively exploited. CISA KEV added 2026-09-10, federal deadline 2026-09-13, known ransomware use: Unknown

Cisco Secure Firewall Management Center (FMC) Software and Security Cloud Control (SCC) Firewall Management — trains 7.0, 7.2, 7.4, 7.6, 7.7, 10.0
Authentication bypass via an alternate path/channel — an improper boot-time system process lets crafted HTTP requests run scripts/commands as root on the underlying OS

Google Chrome before 153.0.8010.36 (V8); every Chromium-based browser and Electron runtime embedding the affected V8 until independently rebuilt
Out-of-bounds write in V8 → arbitrary code execution inside the renderer sandbox via a crafted HTML page
Exploitationyes per CISA KEV (added 2026-09-09, federal deadline 2026-09-23, known ransomware use: Unknown). Google's Chrome Releases post was not readable per-CVE this session, so no vendor in-the-wild statement is recorded either way

improper limitation of a pathname to a restricted directory (CWE-22) → write outside the Docker cache path → container-image cache poisoning → supply-chain execution

Memory overflow (improper restriction of operations within the bounds of a memory buffer) → unpredictable behaviour / denial of service
Exploitationyes — CISA KEV-confirmed (added 2026-08-26, ransomware use: Unknown). Citrix disclosed the flaw in June 2026; KEV membership is the exploitation evidence carrying this card

Linux kernel — algif_aead (AF_ALG crypto user-space interface). Fixed across stable trees; distribution kernels inherit the fix via their own stable-tree rebases
Incorrect resource transfer between spheres (CWE-669, also CWE-1288) in algif_aead — in-place operation across distinct source/destination mappings; upstream fix reverts to out-of-place operation. Local privilege escalation

Patched inFixed upstream in the Linux stable trees — NVD lists eight stable-tree patch commits (git.kernel.org/stable/c/ 19d43105, 3115af96, 893d22e0, 8b88d993, 961cfa27, a664bf3d, ce42ee42, fafe0fa2), read via the NVD API 2026-09-11. There is no single version number: take your distribution's current kernel, which carries the fix through its stable rebase. ⚠️ No specific distribution package versions were verified by this review — confirm against your own vendor's errata. Hardening that reduces exposure regardless: AF_ALG is rarely needed by applications, so blocking the algif_aead module or restricting AF_ALG socket creation removes the attack surface on hosts that do not use it
Improper control of dynamically-managed code resources (CWE-913) in workflow expression evaluation → authenticated RCE as the n8n process

mod_rewrite output-escaping flaw → unintended filesystem mapping and admin session-token hijack (CVE-2024-38475), chained into authenticated OS command injection as 'nobody' (CVE-2023-44221) → unauthenticated arbitrary command execution
Exploitationyes — both CISA KEV-listed (added 2025-05-01, ransomware use: Unknown for both); SonicWall confirmed the two flaws are exploited together in the wild and security researchers publicly documented the full chain

Patched inSonicWall SMA100 firmware 10.2.1.10-62sv and above; Apache HTTP Server 2.4.60 and above. Neither vendor published a workaround beyond upgrading. SMA100 administrators should additionally review for unauthorized logins and rotate admin credentials — the chain grants full device compromise, so a patch alone does not establish that the device is clean
Fortinet FortiOS 7.0.0–7.0.16; FortiProxy 7.0.0–7.0.19 and 7.2.0–7.2.12
Authentication bypass via an alternate path in the Node.js websocket module (CWE-288) → super-admin privileges on the device
Exploitationyes — CISA KEV with knownRansomwareCampaignUse: Known; disclosed by Fortinet as an actively exploited zero-day in January 2025 with rogue admin account creation observed for weeks prior; subsequently tied by CISA and partners to ransomware intrusions including an August 2026 advisory on the Gunra campaign using compromised FortiGate devices for initial access

Patched inFortiOS 7.0.17 and above; FortiProxy 7.0.20 or 7.2.13 and above. No vendor workaround. Any device whose management interface was internet-exposed should have admin credentials rotated — the patch closes the bypass but does not evict an attacker who already created accounts

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