Symfony vulnerable to open redirect via browser-sanitized URLs

  • Disclosed: 06.11.2024
  • Updated: 11.10.2026 10:22

Description

The Request class, does not parse URI with special characters the same way browsers do. As a result, an attacker can trick a validator relying on the Request class to redirect users to another domain.

Resolution

The Request::create methods now assert the URI does not contain invalid characters as defined by https://url.spec.whatwg.org/

The patch for this issue is available here for branch 5.4.

Credits

We would like to thank Sam Mush - IPASSLab && ZGC Lab for reporting the issue and Nicolas Grekas for providing the fix.
