CVE-2026-76461: Critical Cisco Secure Email Gateway Vulnerability Exploited in the Wild

Cisco Secure Email Gateway zero-day CVE-2026-76461 (CVSS 9.8) enables unauthenticated root command execution via crafted email; CISA added it to KEV.

CVE-2026-76461 is a critical SQL injection (CVSS 9.8) in Cisco AsyncOS for Secure Email Gateway allowing an unauthenticated remote attacker to execute arbitrary commands with root privileges by sending a specially crafted email through a vulnerable gateway. CISA added it to the KEV catalog on disclosure day, indicating zero-day exploitation, and Cisco PSIRT became aware of active exploitation in September 2026. No public PoC or attribution exists; fixed versions are 15.5.5-014, 16.0.4-302, and 16.5.0-780, and admins should check mail_logs for suspicious SQL statements like 'COPY.*TO PROGRAM'.

Check Point Patches Critical VPN Vulnerabilities

Check Point patches two critical unauthenticated RCE flaws (CVE-2026-85102, CVE-2026-85103) in VPN gateways and firewalls; no exploitation observed.

Check Point released patches for CVE-2026-85102 and CVE-2026-85103, two critical vulnerabilities (CVSS 9.8) enabling unauthenticated remote code execution in products using VPN functionality. CVE-2026-85102 involves improper validation of certificate data during VPN negotiation, while CVE-2026-85103 is a heap overflow in the VPN certificate ASN.1 decoding flow. Updates cover versions R82.10, R82, and R81.20; manually defining VPN rules is offered as a mitigation, though it does not apply to locally managed Spark Firewall instances. Check Point discovered both flaws internally and reports no evidence of exploitation in the wild.

Critical unauthenticated RCE zero-day CVE-2026-75650 (StyleSmuggler) in Adobe Commerce and Magento is actively exploited; Adobe shipped hotfix VULN-39341 on September 7.

CVE-2026-75650 is a CVSS 10.0 unauthenticated remote code execution flaw in Adobe Commerce 2.4.4-2.4.9, Adobe Commerce B2B 1.3.3-1.5.3, and Magento Open Source 2.4.6-2.4.9, exploited via malicious style properties that inject PHP code executed through a transactional email template. Active exploitation began September 4, 2026, three days before Adobe released Hotfix VULN-39341 (APSB26-146) on September 7, with multiple victim stores confirmed by Sansec and Disrex across at least two distinct campaigns. Attackers deploy a persistent implant at ~/.local/share/.gvfsd/gvfsd-user masquerading as kworker, fc-cache, or chronyd, sustained by a cron job, while a second operator dropped a PHP web shell in product image caches.
