CVE-2026-117611High 7.1

Checkmk: Improper certificate validation in bundled root CA stores

Checkmk trusts a root CA in its bundled CA stores (certifi and, according to some sources, webpki-roots) that chains to eMudhra (emSign) intermediate certificates whose private keys have been compromised. An attacker holding one of these keys could issue certificates for arbitrary host names that would be accepted as valid. Exploitation requires that the attacker can also intercept traffic between Checkmk and a monitored HTTPS endpoint, for example through a man-in-the-middle position.

CVE-2026-14452High 8.6

Checkmk: Open redirect and XSS in Setup in-page search

The reset_url parameter of the Setup in-page search in Checkmk is not validated. An attacker can craft a URL that runs script in the session of a logged-in user with Setup access, or redirects that user to an external site. The attack requires the victim to open the crafted URL and click Reset or submit an empty search.
