An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-14452 in the wild and no public exploit code.\n\nAffected product: 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-2026-14452/ (Markdown: https://insights.sbomify.com/CVE-2026-14452/index.md)","id":"CVE-2026-14452","markdown":"https://insights.sbomify.com/CVE-2026-14452/index.md","name":"CVE-2026-14452","record":{"aliases":["GHSA-v923-r34g-79c7"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IT monitoring software","requires_auth":"none","summary":"Attackers can execute arbitrary scripts or redirect users via the reset_url parameter in Checkmk's setup search, requiring user interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Checkmk","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Improper validation of the reset_url parameter of the Setup in-page search in Checkmk \u003c2.5.0p15, \u003c2.4.0p38, \u003c2.3.0p51 and 2.2.0 (EOL) allows an attacker to execute arbitrary script in the session of an authenticated user with Setup access, or to redirect that user to an arbitrary external site, by tricking the user into opening a crafted URL and clicking the Reset button or submitting an empty search.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Open redirect and XSS via reset_url parameter","id":"CVE-2026-14452","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"A user with low privileges can inject SSTI templates that can lead to RCE in open-tickets","id":"CVE-2026-14453"},"packages":[],"prev":{"headline":"Maas-billing: maas api: privilege escalation via forged http headers due to missing authentication","id":"CVE-2026-14450"},"products":["Checkmk"],"published":"2026-10-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-16","vendors":["Checkmk GmbH"]},"summary":"Attackers can execute arbitrary scripts or redirect users via the reset_url parameter in Checkmk's setup search, requiring user interaction.","url":"https://insights.sbomify.com/CVE-2026-14452/"}
