NVD description

Crawl4AI 0.7.0 before 0.9.4 contains a server-side request forgery vulnerability that allows API clients to reach internal addresses by enabling link_preview_config on /crawl requests. Attackers can supply a controlled page with include_external and include_patterns set, causing AsyncUrlSeeder to fetch internal, private, and cloud-metadata links and return their parsed head data.

🚨High - Crawl4AI SSRF via link_preview_config on /crawl (CVE-2026-109238) Crawl4AI /crawl requests with link_preview_config enabled can be abused to pivot AsyncUrlSeeder into fetching internal/private/cloud-metadata URLs by serving an attacker-controlled page and setting include_external + include_patterns to match sensitive targets, returning parsed <head> data. Instances not exposing the API endpoint aren’t impacted. 👉Affected: crawl4ai >= 0.7.0, < 0.9.4 | Upgrade to 0.9.4
