Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Concurrent access can lead to race conditions where JVM Method objects are temporarily left in an accessible state, or bypass cached SecurityManager checks entirely, enabling unauthorized invocation of sensitive, non-public methods.
Sandbox Bypass: Ineffective sandbox constraints during OGNL evaluation can allow arbitrary, system-level operations to be executed without appropriate custom SecurityManager or AccessController.doPrivileged wrapping.
