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.","state":0,"publishedAt":"2023-02-14T19:47:56.863+00:00","modifiedAt":"2026-10-08T21:14:06.502+00:00","affected":[{"ecosystem":"Vendor product","name":"git","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"git\",\n                    \"product\": \"git\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.39.0, < 2.39.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.38.0, < 2.38.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.37.0, < 2.37.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.36.0, < 2.36.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.35.0, < 2.35.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.34.0, < 2.34.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.33.0, < 2.33.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.32.0, < 2.32.6\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.31.0, < 2.31.7\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"< 2.30.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","score":5.5,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-22490","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-22490","identifiers":["CVE-2023-22490"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
