Upgrade ognl:ognl to version 3.4.13 or higher.
Overview
ognl:ognl is an OGNL - Object Graph Navigation Library.
Affected versions of this package are vulnerable to Protection Mechanism Failure in the stricter-invocation block list enforcement process. An attacker can bypass intended security restrictions by leveraging reflection proxies to invoke blocked methods, potentially leading to unauthorized actions such as code execution, file creation, or system command execution. This is only exploitable if the application evaluates untrusted OGNL expressions, uses the default permissive MemberAccess (or an equivalently permissive one that allows java.lang.reflect), and relies solely on the stricter-invocation block list for sandboxing.
