UBUNTU-CVE-2026-45753 0 A vulnerability in the Symfony PHP framework affects versions from 6.1.0-BETA1 up to but not including 6.4.40, 7.4.12, and 8.0.12. The UrlAttributeSanitizer::getSupportedAttributes() method omits certain URL-valued attributes such as action, formaction, poster, and cite. This omission can allow javascript: URIs to remain unsanitized, potentially enabling cross-site scripting (XSS) when the affected HTML is rendered or when a user interacts with forms or buttons. The issue is fixed in Symfony versions 6.4.40, 7.4.12, and 8.0.12. Multiple Ubuntu package versions of Symfony are affected. No known exploits are reported in the wild.
