CVE-2026-58144Public exploitNetwork attack vector

Stored script execution via unescaped PFS folder titles

Published Jul 9, 2026 · Updated Jul 9, 2026

Stored cross-site scripting in Cotonti Siena 0.9.26 and earlier allows remote authenticated users to run scripts in viewers' browsers. The PFS new-folder handler imports ntitle with the TXT filter, stores it as pff_title, and renders PFF_ROW_TITLE without HTML escaping. PFS write access is required, and the stored payload executes when another user, including an administrator, opens the folder listing.
