Not knowing what it was
And they will keep applying it
Forever just because

Another week; another Fortinet vulnerability.

Fortinet disclosed CVE-2026-104286 on Oct. 1 and confirmed active exploitation. Path-traversal lets unauthenticated attackers write arbitrary files, which can lead to command execution. Until fixes arrive, disable IBE or restrict the management interface to trusted networks. Preserve evidence and review Fortinet’s IoCs; mitigation does not erase a compromise.
