CVE-2026-56258
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk47th percentile — higher than 47% of all known CVEs
Summary
Crawl4AI before version 0.8.8 contains an arbitrary file write vulnerability in the screenshot and PDF endpoints, allowing unauthenticated attackers to write files outside the intended directory.
Risk Assessment
Remote attackers can exploit insufficient path validation and symlink following, leading to arbitrary file write and potential code execution on systems where the runtime user has write access to executable or cron locations.
Recommendation
It is recommended to upgrade to version 0.8.8 or later to mitigate this vulnerability and implement proper path validation mechanisms.
Original NVD description (English source)
Crawl4AI before 0.8.8 contains an arbitrary file write vulnerability in the screenshot and PDF endpoints that allows unauthenticated attackers to write files outside the intended directory via symlink and time-of-check-time-of-use (TOCTOU) attacks on the output_path parameter. Remote attackers can exploit insufficient path validation and symlink following to achieve arbitrary file write and potential code execution on systems where the runtime user has write access to executable or cron locations.
