An attacker needs administrator access to exploit it, 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-2026-29053 exists.\n\nAffected packages and fixed versions:\n- ghost (Bitnami): affected from 0.7.2; fixed in 6.19.1\n- ghost (npm): affected from 0.7.2; fixed in 6.19.1\n- ghost (npm): affected from 0.7.2; fixed in 6.19.1\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-2026-29053/ (Markdown: https://insights.sbomify.com/CVE-2026-29053/index.md)","id":"CVE-2026-29053","markdown":"https://insights.sbomify.com/CVE-2026-29053/index.md","name":"CVE-2026-29053","record":{"aliases":["BIT-ghost-2026-29053","GHSA-cgc2-rcrh-qr5x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ghost CMS","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary code on Ghost servers by uploading malicious themes, requiring an upgrade to the latest version.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"ghost","vendor":"ghost"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Ghost is a Node.js content management system.
