Git · Crawl4Ai · CVE-2026-109239
**Name of the Vulnerable Software and Affected Versions**
Crawl4AI versions prior to 0.9.4
**Description**
A blind server-side request forgery (SSRF) exists in the `can fetch()` function of the RobotsParser. This allows unauthenticated attackers to bypass Docker server egress controls by enabling `check robots txt` and utilizing redirects or DNS rebinding. This technique can be used to access internal, loopback, or cloud-metadata addresses for service discovery. SSRF is a flaw where an attacker can induce the server to make requests to an unintended location.
**Recommendations**
Update to version 0.9.4 or later.
