Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Crawl4AI before 0.8.7 contains an authentication bypass vulnerability in the monitor router endpoints that allows unauthenticated attackers to access destructive operations. Remote attackers can invoke the /monitor/actions/cleanup endpoint and manipulate monitoring state without authentication, causing service disruption.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Crawl4AI versions before 0.8.7 fail to enforce authentication on monitor router endpoints. The /monitor/actions/cleanup endpoint can be invoked by remote unauthenticated attackers, allowing manipulation of monitoring state and causing service disruption through destructive cleanup operations.

MitigationUpgrade to Crawl4AI version 0.8.7 or later. If immediate upgrade is not feasible, implement network-level access controls to restrict access to monitor endpoints until the patch can be applied.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Crawl4AI version
    Run 'pip show crawl4ai' or check your dependency management system for the installed version of Crawl4AI or Kidocode Crawl4ai package
    Affected if The installed version is lower than 0.8.7 (e.g., 0.8.6, 0.8.5, etc.)
  2. Determine if monitor endpoints are enabled
    Inspect your Crawl4AI configuration files or startup scripts for monitor router or dashboard endpoint enablement (look for settings like 'enable_monitor', 'monitor_router', or similar flags)
    Affected if Monitor endpoints are explicitly enabled in the configuration
  3. Test unauthenticated access to monitor cleanup endpoint
    Send an HTTP request to http://<your-host>:<port>/monitor/actions/cleanup using curl or a similar tool without providing any authentication credentials
    Affected if The request returns a successful HTTP response (2xx) rather than 401 Unauthorized or 403 Forbidden, indicating the endpoint is accessible without authentication
  4. Check network exposure of monitor endpoints
    Review firewall rules, reverse proxy configurations, or Kubernetes/network policies to determine if monitor ports are exposed to untrusted networks or the public internet
    Affected if Monitor endpoints are reachable from networks outside the trusted internal environment
  5. Verify authentication middleware on monitor routes
    Inspect the Crawl4AI source code or API gateway configuration to confirm whether authentication/authorization middleware is applied to /monitor/* routes
    Affected if No authentication middleware is configured or enforced on monitor router endpoints

You are affected if Crawl4AI version is below 0.8.7 AND the monitor endpoints are enabled and accessible without authentication credentials.

Generated from the published advisory. Verify against your own configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 0.8.7 or later
Fixed in 0.8.7
Interim mitigation

Upgrade to Crawl4AI version 0.8.7 or later. If immediate upgrade is not feasible, implement network-level access controls to restrict access to monitor endpoints until the patch can be applied.

Recommended fix High confidence

0.8.7

  1. Upgrade Crawl4ai to version 0.8.7 or later to resolve the authentication bypass vulnerability in monitor router endpoints
  2. After upgrading, verify that the /monitor/actions/cleanup endpoint now requires authentication
