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, HtmlSanitizer URL sanitization can allow off-allowlist URLs through allowLinkHosts() or allowMediaHosts() because UrlSanitizer::parse() follows RFC 3986 while browsers follow WHATWG URL parsing, and because <area href> is checked against the media policy rather than the link policy. This issue is fixed in versions 6.4.40, 7.4.12, and 8.0.12.

Affected configurations

• sensiolabs symfony (>= 6.1.0 < 6.4.40) • sensiolabs symfony (>= 7.0.0 < 7.4.12) • sensiolabs symfony (>= 8.0.0 < 8.0.12)
