Fortinet FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability
CVE-2025-68686 · CISA KEV · July 27, 2026
Summary
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.
From CISA, quoted as published. Check the source before acting.
