Highlights

Deserialization of Untrusted Data: 1 prior fix. Scrutinize any change in this area.

KsonDeserializer.java: most-fixed (1 issue). Treat as high-risk during review.

2 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.

Insecure Deserialization: Arbitrary class deserialization via Class.forName can lead to remote code execution; the fix added a ClassSecurityVerifier but only covers this registry path.

Deserialization of Untrusted Data: Unrestricted Class.forName(type) in Kson deserialization allows arbitrary class instantiation; the fix restricts to known/mapped types but only on this path.
