Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A logic error in querying session expiration (< instead of >) caused active sessions to be rejected and expired sessions to be incorrectly treated as valid, leading to severe authentication bypasses.
Cryptographic Issues: Failing to await asynchronous SHA-256 hashing operations during API key and token generation resulted in predictable keys derived from unresolved Promise strings.
Auth Bypass: Using mutable, user-controlled slugs for access control validation instead of immutable unique identifiers allowed potential tenant isolation bypasses.
