Zero-Day CVE-2025-61624, CVE-2026-102764

CISA Flags Actively Exploited BeyondTrust Auth Bypass and Fortinet Path Traversal

CISA has added two vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation. The most identity-relevant is CVE-2026-102764, a BeyondTrust Remote Support authentication bypass by spoofing, which could allow attackers to circumvent authentication controls on a privileged remote-access tool. The second, CVE-2025-61624, is a path traversal flaw affecting multiple Fortinet products.

Authentication bypass issues in remote-support and privileged-access platforms are especially dangerous because such tools often hold elevated rights across managed environments. A spoofing-based bypass can let an attacker impersonate a legitimate session and gain footholds that lead to lateral movement and credential compromise within Active Directory and broader infrastructure.

What to take away: Under BOD 26-04, federal agencies must prioritize rapid remediation of KEV-listed flaws on exposed assets, but all organizations running BeyondTrust Remote Support or affected Fortinet products should patch immediately and hunt for signs of pre-patch compromise, particularly anomalous authentication and remote-access activity.
