CVE-2025-68686

Fortinet FortiOSActively Exploited (CISA KEV)CVSS 5.9KEV0-Day

Actively exploited (CISA KEV) - patch before 2026-08-10

Fortinet FortiOS contains an exposure of sensitive information to an unauthorized actor vulnerability. This may allow a remote unauthenticated attacker to bypass the patch developed for the symbolic link persistency mechanism observed in some post-exploit cases, via crafted HTTP requests. An attacker would need first to have compromised the product via another vulnerability, at filesystem level.

Actively exploited in the wild and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: No fix is published yet for an actively-exploited flaw. Apply vendor mitigations, restrict exposure, and watch for a patch.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
