Summary
Fortinet FortiOS 7.6, 7.4, 7.2, 7.0, and 6.4 releases are affected by this flaw, which lets a remote, unauthenticated attacker bypass a previous fix for a symbolic link persistence mechanism and expose sensitive information through crafted HTTP requests. Exploitation requires the attacker to have already compromised the device at the filesystem level through a separate vulnerability.

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability [CWE-200] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.1, FortiOS 7.4.0 through 7.4.6, FortiOS 7.2 all versions, FortiOS 7.0 all versions, FortiOS 6.4 all versions 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.

Questions about CVE-2025-68686
What does this mean?
A remote attacker who sends crafted HTTP requests, without logging in, can bypass the patch for the symbolic link persistency mechanism and cause information disclosure. The attacker must first have compromised the product through another vulnerability, at filesystem level.Source: fortiguard.fortinet.com
Am I affected, and how do I check?
Affected versions are FortiOS 7.6.0 through 7.6.1, 7.4.0 through 7.4.6, and all 7.2, 7.0, and 6.4 versions. Only products that have had SSL-VPN enabled are impacted, so check the installed FortiOS version and whether SSL-VPN has ever been enabled.Source: fortiguard.fortinet.com
What should I do about it?
Upgrade to FortiOS 7.6.2 or above, which is the fix the advisory lists.Source: fortiguard.fortinet.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2026-07-27, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
