An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-67288 exists.\n\nAffected packages and fixed versions:\n- Umbraco.Cms (NuGet): affected all versions up to 16.3.3; no fix listed\n- Umbraco.Cms (NuGet): affected all versions up to 16.3.3; 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-2025-67288/ (Markdown: https://insights.sbomify.com/CVE-2025-67288/index.md)","id":"CVE-2025-67288","markdown":"https://insights.sbomify.com/CVE-2025-67288/index.md","name":"CVE-2025-67288","record":{"aliases":["GHSA-54mj-vcvj-q3v5"],"analysis":{"component_type":"web_application","fix_type":"configuration_change","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Umbraco CMS","requires_auth":"none","summary":"Attackers may execute arbitrary code via crafted PDF uploads in Umbraco CMS, though the vendor disputes this as an administrator configuration responsibility.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"umbraco_cms","vendor":"umbraco"}],"cvss":{"score":10,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An arbitrary file upload vulnerability in Umbraco CMS v16.3.3 allows attackers to execute arbitrary code by uploading a crafted PDF file.
