Summary

ConvertX, a self-hosted file conversion service, is affected before 0.18.0. The /delete/{id} endpoint performs permanent deletion over HTTP GET and lacks CSRF protection (CWE-352). If an authenticated user visits attacker-controlled content, the browser sends the session cookie and the request deletes the targeted job, causing loss of converted-file history.

Description from the CNA

ConvertX is a self-hosted file conversion service. Prior to 0.18.0, the /delete/{id} endpoint uses HTTP GET for permanent deletion without CSRF protection. If an authenticated user visits attacker-controlled content that requests /delete/{id}, the browser sends the user session cookie and the request deletes the targeted job, resulting in unauthorized loss of converted-file history. This issue is fixed in version 0.18.0.
