CVE-2025-68686: Fortinet FortiOS Exposure of Sensitive Information to an Unauthorized Actor Vulnerability
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: added to CISA’s KEV catalog on July 27, 2026.
- Use by ransomware: not established so far.
- Remediation deadline for US federal agencies: August 10, 2026.
Description from CISA’s KEV catalog.
What to do
- Check whether your estate includes Fortinet FortiOS, including internet-facing devices.
- Apply the vendor’s patch or mitigations (references below). Failing that, isolate the product or stop using it, as CISA requires of US federal agencies.
- An exploited vulnerability has often been used before it was fixed: look for signs of compromise, especially on internet-facing devices.
