CVE-2026-61645: Docat Arbitrary File Upload Vulnerability in Upload API

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

Docat contains an arbitrary file upload vulnerability in the Upload API due to the lack of validation for uploaded file paths or types. This flaw allows attackers to overwrite sensitive configuration files or place malicious files on the web server.

Why does it matter?

The vulnerability enables authenticated users to modify sensitive files on the server, potentially leading to remote code execution or cross-site scripting depending on the deployment context.

What should be done?

Follow vendor advisories and updates
Review version 1.6.0 deployment

Show the technical text from the sources

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.
