CVE-2026-23476Public exploitNetwork attack vector

Authenticated script execution via raw error messages

Published Feb 2, 2026 · Updated Feb 2, 2026

Reflected XSS in FacturaScripts before 2025.8 allows remote authenticated users to execute script in another logged-in user's browser. Core/View/Macro/Utils.html.twig renders database-error messages with Twig's raw filter, so attacker-controlled code values returned in PostgreSQL errors bypass HTML escaping. Any user account can supply a crafted code value, but a logged-in victim must follow the link; injected script can read page data or present a credential form.
