CVE-2026-62960 Git for Windows: Server-advertised bundle-uri can trigger outbound SMB callbacks via UNC and file:// paths on Windows

Git for Windows is the Windows port of Git. Prior to 2.55.0.windows.4, a malicious remote Git server can advertise a bundle URI that reaches transportgetremotebundleuri, fetchbundleuriinternal, and copyuritofile in bundle-uri.c during clone or fetch when transfer.bundleuri=true. Non-HTTPS values...

CVE-2026-62960

Git for Windows prior to 2.55.0.windows.4 is vulnerable to a security bypass in bundle-uri.c . When transfer.bundleuri=true, a malicious remote Git server can advertise a bundle URI processed by transport_get_remote_bundle_uri(), fetch_bundle_uri_internal(), and copy_uri_to_file(). Non-HTTP(S) va...
