Vulnerability details

Uptime Kuma is an open source, self-hosted monitoring tool. From 2.0.0 to 2.1.3 , the GET /api/badge/:id/ping/:duration? endpoint in server/routers/api-router.js does not verify that the requested monitor belongs to a public group. All other badge endpoints check AND public =…

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-1 Policy and Procedures
addresses: CWE-862

Requiring an access control policy ensures authorization checks are defined and applied for critical functions.

AC-13 Supervision and Review — Access Control
addresses: CWE-862

Reviews of access controls detect missing authorization checks on critical functions or resources.

AC-14 Permitted Actions Without Identification or Authentication
addresses: CWE-862

Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.

AC-16 Security and Privacy Attributes
addresses: CWE-862

Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.

AC-17 Remote Access
addresses: CWE-862

Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.

AC-18 Wireless Access
addresses: CWE-862

Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.

AC-19 Access Control for Mobile Devices
addresses: CWE-862

The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.

AC-2 Account Management
addresses: CWE-862

Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
