CVE-2026-30829
No affected components available
Checkmate is an open-source, self-hosted tool designed to track and monitor server hardware, uptime, response times, and incidents in real-time with beautiful visualizations. Prior to version 3.4.0, an unauthenticated information disclosure vulnerability exists in the GET /api/v1/status-page/:url endpoint. The endpoint does not enforce authentication or verify whether a status page is published before returning full status page details. As a result, unpublished status pages and their associated internal data are accessible to any unauthenticated user via direct API requests. This issue has been patched in version 3.4.0.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a low impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
