An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-71285 in the wild and no public exploit code.\n\nAffected product: louislam uptime-kuma. 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-2026-71285/ (Markdown: https://insights.sbomify.com/CVE-2026-71285/index.md)","id":"CVE-2026-71285","markdown":"https://insights.sbomify.com/CVE-2026-71285/index.md","name":"CVE-2026-71285","record":{"aliases":["GHSA-pf4v-rpp4-fp6r"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Uptime Kuma","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary JavaScript on public status pages via Matomo Site ID, stealing cookies and taking over sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Uptime Kuma's Matomo analytics integration (server/analytics/matomo-analytics.js) injects the admin-configurable Matomo value as a bare, unquoted JavaScript expression inside a \u003cscript\u003e block rendered on every public status page.
