Modified 6 days ago

Details

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Prior to 5.4.52, 6.4.40, 7.4.12, and 8.0.12, Crawler::addXmlContent() set DOMDocument::$validateOnParse = true before loadXML(), re-enabling external entity resolution and allowing attacker-supplied XML to expand file:// entities such as local files. This issue is fixed in versions 5.4.52, 6.4.40, 7.4.12, and 8.0.12.
