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-2020-8103 in the wild and no public exploit code.\n\nAffected product: Bitdefender Antivirus Free. 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-2020-8103/ (Markdown: https://insights.sbomify.com/CVE-2020-8103/index.md)","id":"CVE-2020-8103","markdown":"https://insights.sbomify.com/CVE-2020-8103/index.md","name":"CVE-2020-8103","record":{"aliases":["GHSA-r666-694p-fhv2"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bitdefender Antivirus Free","requires_auth":"low_privilege","summary":"An unprivileged user can exploit improper symbolic link handling to restore quarantined files to privileged locations, leading to privilege escalation.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Bitdefender","cpe":[{"product":"antivirus_2020","vendor":"bitdefender"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"A vulnerability in the improper handling of symbolic links in Bitdefender Antivirus Free can allow an unprivileged user to substitute a quarantined file, and restore it to a privileged location.
