CVE-2026-76565MediumCVSS 5.3CVE published 20 August 2026

Phoca Cart (com_phocacart) 6.1.7 - Unauthenticated Reflected XSS in the product price filter

Phoca Cart echoes the price_from and price_to request parameters straight into the value attribute of the product filter text inputs, in the site layouts form_filter_text.php and form_filter_horizontal_text.php, with no escaping. No login is required: a crafted link to a shop category or product list page whose price_from value contains a double quote breaks out of the attribute and runs attacker script in the browser of anyone who opens it. The filter panel is rendered on the public shop pages whenever the price filter is enabled. 6.1.8 wraps both values in htmlspecialchars with ENT_QUOTES and ENT_SUBSTITUTE, and also escapes an unescaped value in the administrator Phoca Render Adminview helper. Confirmed by diffing the released com_phocacart zips on 2026-08-18. Update to 6.1.8. Note that 6.1.7 was itself the fix for the CVE-2026-74251 product filter SQL injection, so a site on 6.1.7 is exposed to this cross site scripting issue only, not to the SQL injection.
