AI-GeneratedThe vulnerability affects Symfony versions from 6.1.0-BETA1 to 6.4.40, as well as 7.4.12 and 8.0.12, specifically in the UrlAttributeSanitizer::getSupportedAttributes() method, which fails to sanitize certain URL-valued attributes. This oversight can lead to cross-site scripting (XSS) attacks, allowing malicious JavaScript to be executed when users interact with affected web applications. Organizations using these versions of Symfony should prioritize updating to the patched versions to mitigate the risk of XSS vulnerabilities.

Original NVD Description
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. From 6.1.0-BETA1 until 6.4.40, 7.4.12, and 8.0.12, UrlAttributeSanitizer::getSupportedAttributes() omits URL-valued attributes including action, formaction, poster, and cite, so configurations that admit those attributes can leave javascript: URIs unsanitized and enable XSS when the resulting HTML is rendered or a victim submits a form or clicks a button. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
