CVE-2026-72567Network attack vectorHinoki check available

Unauthenticated file write and deletion via path traversal

Published Aug 10, 2026 · Updated Aug 10, 2026

Path traversal in AsyncFuncAI DeepWiki-Open through commit 16f35a0 allows remote attackers to write or delete arbitrary files. The get_wiki_cache_path helper interpolates user-controlled owner, repo, repo_type, and language values into a cache filename and joins it to WIKI_CACHE_DIR without sanitization or a containment check. The wiki-cache endpoints require no authentication, and deployments running the API as root expose every file writable or removable by that process.
