In modules/pfs/inc/pfs.editfolder.php, the folder update action ('a=update') updates folder metadata (title, description, public/gallery flags) without calling cot_check_xg() to validate the anti-CSRF token. A remote attacker who lures an authenticated user into visiting a malicious page can force the browser to submit a forged request that modifies the victim's folder metadata, including making a private folder public.\n\n## Affected packages\n\n- `cotonti/cotonti <= 1.0.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
