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, UrlSanitizer::parse() passes Unicode explicit-direction BiDi formatting characters through into sanitized href and src attributes, allowing sanitized content to display a link destination that visually differs from the actual destination and enabling phishing-style visual spoofing. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.
