CVE-2026-90946
HighCVSS 7.5Summary
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.
Risk Assessment
An unauthenticated attacker can read arbitrary files from the system, including configuration files containing secrets and credentials. This can lead to full system compromise.
Recommendation
Update DeepWiki-Open to a version containing the fix or restrict access to the /ws/chat endpoint. Until then, consider disabling the service or placing it behind an authenticating proxy.
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-2026-72602High
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.
