{"id":"CVE-2023-22490","state":"PUBLISHED","title":"Git vulnerable to local clone-based data exfiltration with non-local transports","description":"Git is a revision control system. Using a specially-crafted repository, Git prior to versions 2.39.2, 2.38.4, 2.37.6, 2.36.5, 2.35.7, 2.34.7, 2.33.7, 2.32.6, 2.31.7, and 2.30.8 can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source `$GIT_DIR/objects` directory contains symbolic links, the `objects` directory itself may still be a symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253.\n\nA fix has been prepared and will appear in v2.39.2 v2.38.4 v2.37.6 v2.36.5 v2.35.7 v2.34.7 v2.33.7 v2.32.6, v2.31.7 and v2.30.8. If upgrading is impractical, two short-term workarounds are available. Avoid cloning repositories from untrusted sources with `--recurse-submodules`. Instead, consider cloning repositories without recursively cloning their submodules, and instead run `git submodule update` at each layer. Before doing so, inspect each new `.gitmodules` file to ensure that it does not contain suspicious module URLs.","publishedAt":"2023-02-14T19:47:56.863Z","updatedAt":"2026-10-08T21:14:06.502Z","severity":{"score":5.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["git git"],"affected":[{"vendor":"git","product":"git","versions":[{"version":">= 2.39.0, < 2.39.2","status":"affected"},{"version":">= 2.38.0, < 2.38.4","status":"affected"},{"version":">= 2.37.0, < 2.37.6","status":"affected"},{"version":">= 2.36.0, < 2.36.5","status":"affected"},{"version":">= 2.35.0, < 2.35.7","status":"affected"},{"version":">= 2.34.0, < 2.34.7","status":"affected"},{"version":">= 2.33.0, < 2.33.7","status":"affected"},{"version":">= 2.32.0, < 2.32.6","status":"affected"},{"version":">= 2.31.0, < 2.31.7","status":"affected"},{"version":"< 2.30.8","status":"affected"}]}],"references":["https://github.com/git/git/security/advisories/GHSA-gw92-x3fm-3g3q","https://github.com/git/git/security/advisories/GHSA-3wp6-j8xr-qw85","https://github.com/git/git/commit/c867e4fa180bec4750e9b54eb10f459030dbebfd","https://security.gentoo.org/glsa/202312-15"],"weaknesses":["CWE-59"],"ingestedAt":"2026-10-29T20:05:43.909Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/22xxx/CVE-2023-22490.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2023-22490","state":"PUBLISHED","datePublished":"2023-02-14T19:47:56.863Z","dateUpdated":"2026-10-08T21:14:06.502Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2022-12-29T17:41:28.089Z"},"containers":{"cna":{"title":"Git vulnerable to local clone-based data exfiltration with non-local transports","descriptions":[{"lang":"en","value":"Git is a revision control system.
