CVE-2026-56262Network attack vector

Service interruption via unauthenticated monitor routes

Published Jun 24, 2026 · Updated Jun 24, 2026

Authentication bypass in Crawl4AI before 0.8.7 allows remote attackers to access destructive monitor operations without authentication. The Docker API server mounts the monitor router without the token_dep dependency, leaving every /monitor/* route unguarded. Network reachability alone is sufficient; remote attackers can read monitoring state or trigger cleanup and other control actions, altering state and interrupting service.
