CVE-2026-61645Docat has Arbitrary File Upload exists in Upload API

Updated under an hour ago ()

Does this affect you?

It affects docat-org docat. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

Docat is a tool for hosting versioned static documentation. In the affected implementation, an arbitrary file upload vulnerability in the `Upload API` arises because the API does not validate the `uploaded file path or type`. An attacker can overwrite sensitive configuration files or place malicious files on the Docat web server. Depending on deployment context, uploaded content can enable remote code execution or cross-site scripting intended to steal cookies or redirect users to malicious websites. Version 1.6.0 mitigates filename-based path traversal; remediation of unrestricted file types or deployment-dependent malicious-content effects is not established by the verified patch.
