Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24096 in the wild and no public exploit code.\n\nAffected product: Checkmk Checkmk. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-24096/ (Markdown: https://insights.sbomify.com/CVE-2026-24096/index.md)","id":"CVE-2026-24096","markdown":"https://insights.sbomify.com/CVE-2026-24096/index.md","name":"CVE-2026-24096","record":{"aliases":["GHSA-4fwv-vp29-wx8m","UBUNTU-CVE-2026-24096"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IT monitoring software","requires_auth":"low_privilege","summary":"Low-privileged users can perform unauthorized actions or access sensitive information via Checkmk REST API endpoints due to insufficient permission checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Checkmk","cpe":[{"product":"checkmk","vendor":"checkmk"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-280","name":"Improper Handling of Insufficient Permissions or Privileges"}],"description":"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","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Insufficient permission validation on multiple REST API Quick Setup endpoints","id":"CVE-2026-24096","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"checkmk:checkmk","products":["checkmk:checkmk"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Authenticated Host Enumeration via Observable Response Discrepancy on Agent Register Existing Endpoint","id":"CVE-2026-24097"},"packages":[],"prev":{"headline":"Missing Permission Check on Analyze Configuration Page","id":"CVE-2026-24095"},"products":["Checkmk"],"published":"2026-04-01","related":[{"cvss_score":9.3,"headline":"omd: Local privilege escalation when executing omd commands as root","id":"CVE-2025-39666","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":9.2,"headline":"Fix 2FA bypass via RestAPI","id":"CVE-2024-8606","kev_date_added":null,"published":"2024-09-23"},{"cvss_score":9.1,"headline":"PHP code injection in watolib","id":"CVE-2022-46836","kev_date_added":null,"published":"2023-02-20"},{"cvss_score":8.8,"headline":"Privilege Escalation in Windows License plugin for Checkmk Windows Agent","id":"CVE-2025-32919","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":8.8,"headline":"Privilege escalation in Windows agent","id":"CVE-2024-28827","kev_date_added":null,"published":"2024-07-10"},{"cvss_score":8.8,"headline":"1-Click compromize via CSRF","id":"CVE-2024-28828","kev_date_added":null,"published":"2024-07-10"},{"cvss_score":8.8,"headline":"Unrestricted upload and download paths in check_sftp","id":"CVE-2024-28826","kev_date_added":null,"published":"2024-05-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-01","vendors":["Checkmk GmbH"]},"summary":"Low-privileged users can perform unauthorized actions or access sensitive information via Checkmk REST API endpoints due to insufficient permission checks.","url":"https://insights.sbomify.com/CVE-2026-24096/"}
