It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-40776 in the wild and no public exploit code.\n\nAffected product: Adobe Lightroom Classic. 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-2021-40776/ (Markdown: https://insights.sbomify.com/CVE-2021-40776/index.md)","id":"CVE-2021-40776","markdown":"https://insights.sbomify.com/CVE-2021-40776/index.md","name":"CVE-2021-40776","record":{"aliases":["GHSA-94qm-cpmj-pvcv"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Adobe Lightroom Classic","requires_auth":"high_privilege","summary":"An authenticated attacker can escalate privileges via DLL hijacking in the offline installer, requiring user interaction during installation.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"lightroom","vendor":"adobe"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-379","name":"Creation of Temporary File in Directory with Insecure Permissions"}],"description":"Adobe Lightroom Classic 10.3 (and earlier) are affected by a privilege escalation vulnerability in the Offline Lightroom Classic installer.
