CVE-2026-112363
Crawl4AI from 0.8.7 through 0.9.5 contains a server-side request forgery vulnerability in the Docker API server that allows unauthenticated attackers to bypass destination checks via URL userinfo parsing differences.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
Crawl4AI from 0.8.7 through 0.9.5 contains a server-side request forgery vulnerability in the Docker API server that allows unauthenticated attackers to bypass destination checks via URL userinfo parsing differences. Attackers can set fetch_ssl_certificate=true with crafted userinfo URLs so SSLCertificate.from_url connects to internal hosts on port 443, probing reachability and leaking certificate details.
