Detect authentication bypass vulnerabilities in Python code by analyzing authentication flows, permission checks, and access control logic. This process identifies improper JWT verification, SSO/OAuth flaws, and decorator-based protection bypasses.

Common CWEs for authorization bypass include CWE-285 for improper authorization, CWE-287 for improper authentication, and CWE-863 for incorrectly implemented security checks. These target flaws in access control logic and token validation.

Audit OAuth and SSO implementations for permission check flaws by analyzing authentication flows and access control logic in Python code. This identifies weak session handling and improper permission checks that allow unauthorized access to privileged actions.

Identify improper JWT validation and token verification issues automatically by scanning Python code for authentication bypass patterns. The analysis targets incorrect token validation implementations that expose sensitive resources.

Prevent decorator-based protection bypass in Python APIs by analyzing access control logic to ensure decorators properly enforce permission checks. This identifies gaps where attackers exploit weak session handling to reach administrative functions.
