{"id":"ALPINE-CVE-2023-22490","details":"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.","modified":"2026-09-15T08:17:48.360383057Z","published":"2023-02-14T20:15:16.683Z","upstream":["CVE-2023-22490"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-22490"}],"affected":[{"package":{"name":"git","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.32.6-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.34.7-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.36.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.38.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}},{"package":{"name":"git","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/git?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.31.0"},{"fixed":"2.39.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-22490.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
