Crawl4AI from 0.9.0 before 0.9.5 contains a JavaScript injection vulnerability in the Docker API server that allows authenticated API clients to run arbitrary JavaScript in the crawl page via allowlisted css_selector and wait_for fields. Attackers can inject quotes into css_selector or supply js: conditions in wait_for, bypassing the js_code block to alter page state and returned crawl content.
