## Technical details

The vulnerability exists in the GET /codemap/file endpoint, where the repo_url parameter fails to properly validate and sanitize user input. By supplying a non-URL value or absolute file path, attackers can bypass path containment checks and read arbitrary files. The endpoint does not require authentication, making this trivially exploitable over the network.
