It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8919 in the wild and no public exploit code.\n\nAffected product: Gerrit. 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-2020-8919/ (Markdown: https://insights.sbomify.com/CVE-2020-8919/index.md)","id":"CVE-2020-8919","markdown":"https://insights.sbomify.com/CVE-2020-8919/index.md","name":"CVE-2020-8919","record":{"aliases":["GHSA-xh5j-7f7g-7g5c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Gerrit code review","requires_auth":"low_privilege","summary":"An attacker with default privileges can read other users' personal account data and restricted sub-trees due to a missing access check in the branch REST API.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"gerrit","vendor":"google"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"An information leak vulnerability exists in Gerrit versions prior to 2.15.21, 2.16.25, 3.0.15, 3.1.10, 3.2.5 where a missing access check on the branch REST API allows an attacker with only the default set of priviledges to read all other user's personal account data as well as sub-trees with restricted access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Information leakage in Gerrit","id":"CVE-2020-8919","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2020"},"n_packages":0,"n_references":6,"next":{"headline":"Overoptimization leads to private information leak in Gerrit","id":"CVE-2020-8920"},"packages":[],"prev":{"headline":"TPM 1.2 key authorization values are vulnerable to a TPM transport eavesdropper","id":"CVE-2020-8918"},"products":["Gerrit"],"published":"2020-12-10","related":[{"cvss_score":6.5,"headline":"Heap Memory exhaustion in Gerrit","id":"CVE-2021-22553","kev_date_added":null,"published":"2021-02-17"},{"cvss_score":6,"headline":"Improper Authorization in Gerrit allowing Code Review Bypass via \"Submitted Together\"","id":"CVE-2026-2725","kev_date_added":null,"published":"2026-05-13"},{"cvss_score":3.5,"headline":"Overoptimization leads to private information leak in Gerrit","id":"CVE-2020-8920","kev_date_added":null,"published":"2020-12-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["Gerrit"]},"summary":"An attacker with default privileges can read other users' personal account data and restricted sub-trees due to a missing access check in the branch REST API.","url":"https://insights.sbomify.com/CVE-2020-8919/"}
