Authenticated script execution via unescaped return policy
Published Dec 17, 2025 · Updated Dec 17, 2025
Stored XSS in Open Source Point of Sale 3.4.0 through 3.4.1 allows remote authenticated users to execute JavaScript through receipts. The receipt and invoice templates pass the stored Return Policy value through nl2br() without HTML escaping, preserving attacker-supplied tags and event handlers. Store Configuration access is required, and viewing or generating a receipt executes the payload in staff browsers, enabling session theft or actions as the victim.
