Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
XML External Entity (XXE): Insecurely configured XML input factories and transformers allow external entity resolution, exposing the application to XXE-based local file read or SSRF attacks.
Auth Bypass: Flaws in JWT and token generation logic, such as referencing incorrect payload variables, can lead to token generation missing security policies or including incorrect authorizations.
Signature Bypass: An incorrect encoding scheme used during signature verification allows malicious requests to bypass webhook validation checks.
