Cotonti CSRF in PFS allows forced arbitrary file upload

Published Jun 18, 2026 · Updated Aug 10, 2026 · Assigned by TuranSec

Description

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the Personal File Storage (PFS) module. In modules/pfs/inc/pfs.main.php, the file upload action ('a=upload') processes uploaded files without calling cot_check_xg to validate the anti-CSRF token, even though sibling actions such as 'delete' (line 272) do.
