Additional Advisory Data
Solutions
CNA: It is strongly recommended to address the vulnerability by upgrading to the latest version. Upgrade to 6.2.6.Final, 7.0.6.Final, 8.0.6.Final, 9.0.2.Final, 9.1.5.Final or later. For more information see: https://github.com/hibernate/hibernate-validator/security/advisories/GHSA-gv36-fx3r-29p5
Workarounds
CNA: The safe alternative for custom validators is to use `addExpressionVariable` instead of `addMessageParameter` when injecting user-controlled values into EL-enabled messages, as expression variables are bound as typed objects and are never re-parsed as EL expressions.
