7 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sandbox Escape: The custom SecurityManager's execution blocking mechanism was repeatedly bypassed due to flawed state tracking (negative integer values and a non-reentrant boolean flag) that allowed nested operations to prematurely unblock command execution.
Command Injection: Integrating third-party command-line utilities via ProcessBuilder is highly risky if arguments are formatted dynamically. Using arbitrary string parameters allowed malicious command execution, requiring a transition to hardcoded boolean switches.
Auth Bypass: The privilege verification logic relied on inspecting class frames from the call stack, which broke on JDK-15 due to altered stack frame depths, allowing unauthorized classes to pass security checks.
