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-2026-70596 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ghost (Bitnami): affected from 4.9.0; fixed in 6.54.1\n- ghost (npm): affected from 4.9.0; fixed in 6.54.1\n- ghost (npm): affected from 4.9.0; fixed in 6.54.1\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-2026-70596/ (Markdown: https://insights.sbomify.com/CVE-2026-70596/index.md)","id":"CVE-2026-70596","markdown":"https://insights.sbomify.com/CVE-2026-70596/index.md","name":"CVE-2026-70596","record":{"aliases":["BIT-ghost-2026-70596","GHSA-pr22-p9rp-2cqv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Ghost CMS","requires_auth":"high_privilege","summary":"An XSS vulnerability in Ghost CMS allows staff users to hijack other staff sessions via feature image captions, leading to privilege escalation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Ghost is a Node.js content management system.
