Summary
Pachno 1.0.6 contains a CSRF vulnerability that allows attackers to perform arbitrary actions in an authenticated user's context by exploiting missing CSRF protections on state-changing endpoints. Attackers can craft malicious requests targeting login, registration, file upload, milestone editing, and administrative functions.
