CVSS Score
-The vulnerability occurs in the credential endpoint handler that directly reflects the user-supplied 'id' parameter in error messages without proper sanitization. The code pattern matches security advisory examples showing unsanitized parameter reflection (res.status(404).send(Credential ${req.params.id} not found)). This is a textbook reflected XSS scenario where attacker-controlled input gets rendered in HTML responses. The GitHub Security Lab report (GHSL-2023-248) specifically identifies this endpoint as vulnerable, and the line numbers in referenced code match error response patterns.
