Unauthenticated file disclosure via unvalidated URL schemes
Published Feb 12, 2026 · Updated Feb 12, 2026
Path traversal in Crawl4AI Docker API before 0.8.0 allows remote attackers to read server files through unauthenticated requests. The four endpoints pass caller-supplied file:// URLs to browser processing without restricting the scheme to remote web content. Exposure requires the self-hosted Docker API to be network-reachable; successful requests disclose container files, including configuration and environment secrets.
