3 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: Proxy and dispatcher classes were generated without a restricted, non-privileged ProtectionDomain, allowing sandbox escapes via class definition. Developers should ensure dynamic class definitions explicitly enforce minimal privileges.
Auth Bypass: Exposing JVM agent instrumentation to unauthorized code allows complete sandbox escape. A strict SecurityManager permission check must guard access to the installer's instrumentation instance.
Auth Bypass: Checksum validation for wrapper binaries on Windows was fragile or bypassed due to localized command output parsing. Command executions like certUtil must be parsed robustly (e.g., using PowerShell index-based selection) to ensure mandatory signature validation.
