Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete logical type-to-class resolution during message decoding allows signature verification checks to be bypassed, potentially leading to the processing of unauthorized or altered message envelopes.
Auth Bypass: A flaw in the decoding pipeline allowed the inner deserializer to process payloads before verifying their cryptographic signature, exposing the application to unsafe deserialization of untrusted data.
Information Disclosure: Exception messages thrown during invalid transport DSN parsing can leak sensitive credentials (usernames, passwords, and tokens) in cleartext through standard error logs and debug outputs.
