- More information:
Jakub Zalas discovered that Symfony, a framework to create websites and web applications, was vulnerable to restriction bypass. It was affecting applications with ESI or SSI support enabled, that use the FragmentListener. A malicious user could call any controller via the /_fragment path by providing an invalid hash in the URL (or removing it), bypassing URL signing and security rules.
