What is CVE-2026-26217?

Crawl4AI versions before 0.8.0 are vulnerable to a local file inclusion flaw within the Docker API deployment. This vulnerability is manifested through endpoints such as /execute_js, /screenshot, /pdf, and /html, which improperly process file:// URLs. As a result, unauthenticated remote attackers may exploit this flaw to access arbitrary files from the server's filesystem. This could lead to exposure of sensitive information such as /etc/passwd, /etc/shadow, and environmental variables. Such access can unveil critical credentials, API keys, and even internal application structure, making it imperative for users to upgrade to the patched version.

Affected Version(s)

Crawl4AI 0 < 0.8.0
