CVE-2026-40041

Pachno 1.0.6 contains a cross-site request forgery vulnerability that allows attackers to perform arbitrary actions in authenticated user 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 to force logout, create accounts, modify roles, inject comments, or upload files when authenticated users visit attacker-controlled websites.
