CVE-2026-109237 Details

Description

Crawl4AI from 0.9.0 before 0.9.4 contains an untrusted-config gate bypass that allows non-admin API clients to construct forbidden config objects by wrapping them in dict-type wrappers. Attackers can send a laundered LLMConfig with api_token set to an env reference via /config/dump to read SECRET_KEY and provider keys, enabling admin JWT forgery.
