Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sandbox Escape: Two fixes wrapped timezone resource loading in doPrivileged blocks to prevent sandbox escape via privileged resource access, but only specific call sites were patched.
Auth Bypass: Global time provider and converter state can be modified without authorization unless a SecurityManager permission check is enforced, risking time manipulation and converter injection.
