May 25, 2018 • Published by Fabien Potencier
Affected versions
Symfony 2.7.0 to 2.7.47, 2.8.0 to 2.8.40, 3.3.0 to 3.3.16, 3.4.0 to 3.4.10, and 4.0.0 to 4.0.10 versions of the Symfony Security component are affected by this security issue.
The issue has been fixed in Symfony 2.7.48, 2.8.41, 3.3.17, 3.4.11, and 4.0.11. 4.1.0 has also been fixed before its final release.
Note that no fixes are provided for Symfony 3.0, 3.1, and 3.2 as they are not maintained anymore.
Description
This is a continuation of
CVE-2017-16652,
where we missed an edge case (when the security.http_utils
was inlined by the container).
Resolution
The fix solves the issue for the edge case.
