Prior to 2.55.0.windows.4, a malicious remote Git server can advertise a bundle URI that reaches transport_get_remote_bundle_uri(), fetch_bundle_uri_internal(), and copy_uri_to_file() in bundle-uri.c during clone or fetch when transfer.bundleuri=true. Non-HTTP(S) values are treated as local filesystem paths, and file URI prefixes are removed, so a bare UNC path or file URI targeting an attacker-controlled share causes Windows to initiate an outbound SMB connection. This can expose NTLM authentication material to the attacker-selected host. This issue is fixed in version 2.55.0.windows.4.","published":"2026-08-21T20:16:38.700","modified":"2026-08-21T20:16:38.700","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/git-for-windows/git/commit/a93524749d7806870fd2b4b00a3812da1d6e5f4a","label":"git-for-windows/git@a935247"},"references":[{"type":"WEB","url":"https://github.com/git-for-windows/git/commit/a93524749d7806870fd2b4b00a3812da1d6e5f4a"},{"type":"WEB","url":"https://github.com/git-for-windows/git/releases/tag/v2.55.0.windows.4"},{"type":"WEB","url":"https://github.com/git-for-windows/git/security/advisories/GHSA-xrpg-8j9v-v282"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-21T20:16:38.700"}}
