CVE-2026-72567 [CRITICAL] – An improper path validation vulnerability in AsyncFuncAI/deepwiki-open through commit 16f3

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 api/api.py wiki-cache endpoint constructs file paths from user-controlled owner, repo, and repo_type fields without sanitization, enabling path traversal.
