CVE-2026-56260Network attack vector

Arbitrary file overwrite via unrestricted output paths

Published Jul 12, 2026 · Updated Jul 12, 2026

Path traversal in the Crawl4AI Docker API server before 0.8.7 allows remote attackers to overwrite writable server files. The /screenshot and /pdf endpoints accept an unvalidated output_path value for filesystem writes, including absolute paths and traversal sequences outside the intended output directory. No authentication or user interaction is required; Docker API exposure permits service interruption by overwriting files accessible to the application user.
