Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45011 exists.\n\nAffected packages and fixed versions:\n- apostrophe (npm): affected all versions; no fix listed\n- apostrophe (npm): affected all versions; no fix listed\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-2026-45011/ (Markdown: https://insights.sbomify.com/CVE-2026-45011/index.md)","id":"CVE-2026-45011","markdown":"https://insights.sbomify.com/CVE-2026-45011/index.md","name":"CVE-2026-45011","record":{"aliases":["GHSA-5f64-7vfc-rcx6"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js CMS","requires_auth":"low_privilege","summary":"An editor can inject malicious JavaScript via image widget links, allowing arbitrary code execution in victims' browsers upon interaction.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"ApostropheCMS is an open-source Node.js content management system.
