DeepWiki-Open through commit d92819a contains an unauthenticated arbitrary file read vulnerability in the GET /codemap/file endpoint via the repo_url parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description

Attackers can supply a non-URL repo_url value to bypass path containment checks and read any file accessible to the API process by specifying absolute file paths.
