Summary
DeepWiki-Open through commit d92819a contains an unauthenticated arbitrary file read vulnerability in the GET /codemap/file endpoint via the repo_url parameter. 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.
Risk Assessment
An unauthenticated attacker could read sensitive files from the server, potentially leaking data including credentials and configuration. This may lead to further attacks and system compromise.
Recommendation
Update DeepWiki-Open to a fixed version or restrict access to the /codemap/file endpoint. Implement validation of the repo_url parameter and limit API process privileges.
Other vulnerabilities in DeepWiki-Open
See all- CVE-2026-72567Critical
An improper path validation vulnerability in AsyncFuncAI/deepwiki-open through commit 16f35a0 allows unauthenticated remote attackers to write to or delete arbitrary files with root privileges. The wiki-cache endpoint constructs file paths from user-controlled fields without sanitization, enabling path traversal.
- CVE-2026-90946High
DeepWiki-Open through commit d92819a contains an arbitrary file read vulnerability in the unauthenticated /ws/chat WebSocket endpoint that accepts repo_url as a filesystem path with no containment. Attackers can supply arbitrary directory paths to read all files with supported extensions including Python, JavaScript, YAML, and JSON files containing hardcoded secrets and credentials.
- CVE-2026-72602High
A path traversal vulnerability in AsyncFuncAI deepwiki-open through commit 16f35a0 allows unauthenticated remote attackers to obtain directory listings for arbitrary filesystem paths via the local-repository structure endpoint. The endpoint accepts an absolute filesystem path parameter and returns a directory listing without authentication, as WIKI_AUTH_MODE defaults to false. An attacker can enumerate sensitive directory contents on the host system.
