Cotonti stored XSS via PFS folder title

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

Description

Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to stored Cross-Site Scripting in the Personal File Storage (PFS) module. A folder title (pff_title) is imported with the 'TXT' filter, which does not strip or encode HTML (the tag check in cot_import is disabled), so an authenticated user can store HTML/JavaScript in a folder title.
