auditor-bundle, formerly known as DoctrineAuditBundle, integrates auditor library into any Symfony 3.4+ application. Prior to version 5.2.6, there is an unescaped entity property enabling Javascript injection. This is possible because `%source_label%` in twig macro is not escaped. Therefore script tags can be inserted and are executed. The vulnerability is fixed in versions 6.0.0 and 5.2.6.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
