This vulnerability can lead to unauthorized method invocation on application beans during the evaluation of mail task body fields, posing a significant risk to application integrity. Organizations using affected versions should prioritize remediation to mitigate potential exploitation risks.

Original NVD Description

Activiti through 7.1.0.M6 fails to validate hash-brace deferred expressions in process variables, allowing attackers to bypass expression filtering. Attackers can inject expressions beginning with #{ that are stored and later evaluated in the full Spring context when a mail task uses variable-backed body fields, enabling method invocation on application beans.
