Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Multiple authorization bypasses were fixed across both C# and Python codebases, including missing checks on agent endpoints, incorrect agent identity verification, inverted admin logic, and misplaced access control checks. These are high-impact because they allow unauthorized access to sensitive operations.
Information Disclosure: Secret values were exposed through serialization, logging, and deployment outputs. Multiple fixes address redaction and keyvault migration, but the risk remains high if any path misses these protections.
Auth Bypass: Authorization logic in the Python API had multiple flaws: inverted admin check, access control not running for all requests, and missing application_id requirement. These are subtle logic errors that are easy to reintroduce.
