| CVE-2026-20915 | 1 Checkmk | 1 Checkmk | 2026-07-25 | N/A | 5.4 MEDIUM |
| Stored cross-site scripting (XSS) in Checkmk version 2.5.0 (beta) before 2.5.0b2 allows authenticated users with permission to create pending changes to inject malicious JavaScript into the Pending Changes sidebar, which will execute in the browsers of other users viewing the sidebar. | |||||
| CVE-2026-33276 | 1 Checkmk | 1 Checkmk | 2026-07-24 | N/A | 5.4 MEDIUM |
| Stored cross-site scripting (XSS) in Checkmk 2.5.0 (beta) before 2.5.0b2 allows authenticated users with permission to create hosts or services to execute arbitrary JavaScript in the browsers of other users performing searches in the Unified Search feature. | |||||
| CVE-2021-40906 | 2 Checkmk, Tribe29 | 2 Checkmk, Checkmk | 2026-07-09 | 4.3 MEDIUM | 6.1 MEDIUM |
| CheckMK Raw Edition software (versions 1.5.0 to 1.6.0) does not sanitise the input of a web service parameter that is in an unauthenticated zone. This Reflected XSS allows an attacker to open a backdoor on the device with HTML content and interpreted by the browser (such as JavaScript or other client-side scripts) or to steal the session cookies of a user who has previously authenticated via a man in the middle. Successful exploitation requires access to the web service resource without authentication. | |||||
| CVE-2021-40905 | 2 Checkmk, Tribe29 | 2 Checkmk, Checkmk | 2026-07-09 | 6.8 MEDIUM | 8.8 HIGH |
| The web management console of CheckMK Enterprise Edition (versions 1.5.0 to 2.0.0p9) does not properly sanitise the uploading of ".mkp" files, which are Extension Packages, making remote code execution possible. Successful exploitation requires access to the web management interface, either with valid credentials or with a hijacked session of a user with administrator role. NOTE: the vendor states that this is the intended behavior: admins are supposed to be able to execute code in this manner. | |||||
| CVE-2021-40904 | 1 Checkmk | 1 Checkmk | 2026-07-09 | 6.8 MEDIUM | 8.8 HIGH |
| The web management console of CheckMK Raw Edition (versions 1.5.0 to 1.6.0) allows a misconfiguration of the web-app Dokuwiki (installed by default), which allows embedded php code. As a result, remote code execution is achieved. Successful exploitation requires access to the web management interface, either with valid credentials or with a hijacked session by a user with the role of administrator. | |||||
| CVE-2026-3466 | 1 Checkmk | 1 Checkmk | 2026-06-17 | N/A | 5.4 MEDIUM |
| Insufficient sanitization of dashboard dashlet title links in Checkmk 2.2.0 (EOL), Checkmk 2.3.0 before 2.3.0p46, Checkmk 2.4.0 before 2.4.0p25, and Checkmk 2.5.0 (beta) before 2.5.0 allows an attacker with dashboard creation privileges to perform stored cross-site scripting (XSS) attacks by tricking a victim into clicking a crafted dashlet title link on a shared dashboard. | |||||
| CVE-2026-3103 | 1 Checkmk | 1 Checkmk | 2026-06-17 | N/A | 5.4 MEDIUM |

| Improper permission enforcement in Checkmk versions 2.4.0 before 2.4.0p23, 2.3.0 before 2.3.0p43, and 2.2.0 (EOL) allows unauthenticated users to enumerate existing hosts by observing different HTTP response codes in deploy_agent endpoint, which could lead to information disclosure. | |||||
| CVE-2026-24097 | 1 Checkmk | 1 Checkmk | 2026-06-17 | N/A | 4.3 MEDIUM |
| Improper permission enforcement in Checkmk versions 2.4.0 before 2.4.0p23, 2.3.0 before 2.3.0p43, and 2.2.0 (EOL) allows authenticated users to enumerate existing hosts by observing different HTTP response codes in agent-receiver/register_existing endpoint, which could lead to information disclosure. | |||||
| CVE-2026-24096 | 1 Checkmk | 1 Checkmk | 2026-06-17 | N/A | 8.8 HIGH |
| Insufficient permission validation on multiple REST API Quick Setup endpoints in Checkmk 2.5.0 (beta) before version 2.5.0b2 and 2.4.0 before version 2.4.0p25 allows low-privileged users to perform unauthorized actions or obtain sensitive information | |||||
