CVE-2026-56262 · Severity: medium · CVSS 6.5 · Published 2026-06-24

Crawl4AI, an open-source web crawling tool, contains a security flaw in its monitoring interface. This vulnerability allows unauthorized individuals to access administrative monitoring functions without a password. An attacker could use this access to disrupt services or perform destructive cleanup operations, potentially impacting the availability of the crawling infrastructure.

## Technical details

An authentication bypass vulnerability exists in the Crawl4AI Docker API server due to missing security dependencies on the monitor router. Specifically, the router was mounted without the 'token_dep' dependency, leaving endpoints such as /monitor/actions/cleanup and the WebSocket /monitor/ws accessible without a valid token. A remote, unauthenticated attacker can exploit this to manipulate the monitoring state or trigger destructive actions. This issue is classified as CWE-306 (Missing Authentication for Critical Function). The vulnerability is resolved in version 0.8.7 by adding the necessary dependency checks to the monitor router and WebSocket endpoints.
