Vulnerability Title
Uptime Kuma is Missing Authorization Checks on Ping Badge Endpoint, Leaks Ping times of monitors without needing to be on a status page
Source: CVE Program / CVE List V5
Vulnerability Description
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 = 1 in their SQL query before returning data. The ping endpoint skips this check entirely, allowing unauthenticated users to extract average ping/response time data for private monitors. This vulnerability is fixed in 2.2.0.

II. Public POCs for CVE-2026-32230

# POC Description Source Link Shenlong Link
1 Uptime-Kuma before v1.23.0 is vulnerable to an information disclosure issue due to missing authorization on the /api/badge/1/ping/24 endpoint. An unauthenticated attacker can access this endpoint to leak ping statistics, such as average ping and ping history, for existing monitors without needing access to the protected status page. This can lead to unintended exposure of internal monitoring data. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-32230.yaml POC Details
