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-2026-40212 in the wild and no public exploit code.\n\nAffected product: OpenStack Skyline. 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-2026-40212/ (Markdown: https://insights.sbomify.com/CVE-2026-40212/index.md)","id":"CVE-2026-40212","markdown":"https://insights.sbomify.com/CVE-2026-40212/index.md","name":"CVE-2026-40212","record":{"aliases":["GHSA-h7hj-cr59-59c2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenStack Skyline","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary scripts in the console web interface via DOM-based XSS, potentially compromising administrator sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"OpenStack Skyline before 5.0.1, 6.0.0, and 7.0.0 has a DOM-based Cross-Site Scripting (XSS) vulnerability in the console because document.write is used unsafely, which is relevant in scenarios where administrators use the console web interface to view instance console logs.","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":"Cross-site scripting in Skyline","id":"CVE-2026-40212","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"OpenStack Cyborg uses rule:allow (check_str='@') as the default policy for multiple API endpoints","id":"CVE-2026-40213"},"packages":[],"prev":{"headline":"Denial of service via crafted DoH3 queries","id":"CVE-2026-40211"},"products":["Skyline"],"published":"2026-04-10","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":"partial"},"state":"PUBLISHED","updated":"2026-04-10","vendors":["OpenStack"]},"summary":"An attacker can execute arbitrary scripts in the console web interface via DOM-based XSS, potentially compromising administrator sessions.","url":"https://insights.sbomify.com/CVE-2026-40212/"}
