An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-103290 in the wild and no public exploit code.\n\nAffected product: TryGhost Ghost. 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-2026-103290/ (Markdown: https://insights.sbomify.com/CVE-2026-103290/index.md)","id":"CVE-2026-103290","markdown":"https://insights.sbomify.com/CVE-2026-103290/index.md","name":"CVE-2026-103290","record":{"aliases":["GHSA-phq3-mc75-42c3"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ghost blog platform","requires_auth":"high_privilege","summary":"Authenticated staff users can exploit insufficient input validation in the ImageSize service to access local files outside intended directories.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-35","name":"Path Traversal: '.../...//'"}],"description":"Ghost versions 6.14.0 through versions prior to 6.27.0 contain a path traversal vulnerability in the ImageSize service.
