An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-103276 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ghost (Bitnami): affected all versions; fixed in 6.20.0\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-2026-103276/ (Markdown: https://insights.sbomify.com/CVE-2026-103276/index.md)","id":"CVE-2026-103276","markdown":"https://insights.sbomify.com/CVE-2026-103276/index.md","name":"CVE-2026-103276","record":{"aliases":["BIT-ghost-2026-103276","GHSA-6v8p-3jx9-8chr","GHSA-v575-g66p-vj84"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ghost CMS","requires_auth":"none","summary":"Unauthenticated attackers can bypass file extension filters using URL encoding to read sensitive theme templates and metadata in Ghost CMS.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-173","name":"Improper Handling of Alternate Encoding"}],"description":"Ghost versions before 6.20.0 contain a file extension filtering bypass vulnerability that allows unauthenticated attackers to read theme templates and metadata.
