Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-7186 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-2026-7186/ (Markdown: https://insights.sbomify.com/CVE-2026-7186/index.md)","id":"CVE-2026-7186","markdown":"https://insights.sbomify.com/CVE-2026-7186/index.md","name":"CVE-2026-7186","record":{"aliases":["GHSA-6f3j-vw42-8645","UBUNTU-CVE-2026-7186"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Checkmk monitoring","requires_auth":"low_privilege","summary":"Stored XSS in Checkmk allows attackers with dashboard edit rights to execute scripts in other users' browsers via malicious URLs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Checkmk","cpe":[{"product":"checkmk","vendor":"checkmk"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Stored cross-site scripting in the URL dashboard widget in Checkmk \u003c2.5.0p5, \u003c2.4.0p31, \u003c2.3.0p48, and all 2.2.0 versions allows a user with dashboard editing permissions to store a URL with a dangerous URI scheme such as javascript: that executes scripts in other users' browsers when they view the dashboard.","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":"Fix stored XSS in URL dashboard widget via dangerous URI schemes","id":"CVE-2026-7186","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"checkmk:checkmk","products":["checkmk:checkmk"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Authentication in Universal Sotware's UKBS","id":"CVE-2026-7187"},"packages":[],"prev":{"headline":"Unauthorized access to files in T-Systems products","id":"CVE-2026-7185"},"products":["Checkmk"],"published":"2026-06-08","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":"total"},"state":"PUBLISHED","updated":"2026-06-08","vendors":["Checkmk GmbH"]},"summary":"Stored XSS in Checkmk allows attackers with dashboard edit rights to execute scripts in other users' browsers via malicious URLs.","url":"https://insights.sbomify.com/CVE-2026-7186/"}
