{"id":"UBUNTU-CVE-2026-123532","details":"gix-fs in gitoxide before 0.24.1 contains a credential disclosure vulnerability that allows remote attackers to capture NTLM credentials by supplying UNC symlink targets in a crafted repository. When a victim checks out the repository on Windows with symlinks enabled, gix_fs::symlink::create calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.","modified":"2026-11-10T02:49:53.288309754Z","published":"2026-11-09T00:00:00Z","upstream":["CVE-2026-123532"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-123532"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-123532"},{"type":"REPORT","url":"https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-xw69-xv93-5fjv"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/gix-fs-before-0.24.1-ntlm-credential-disclosure-via-windows-symlink-unc-probe"}],"affected":[{"package":{"name":"rust-gix-fs","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-gix-fs?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.8.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.8.0-1","binary_name":"librust-gix-fs-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-123532.json"}},{"package":{"name":"rust-gix-fs","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/rust-gix-fs?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.16.1-1","0.21.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.21.1-1","binary_name":"librust-gix-fs-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-123532.json"}},{"package":{"name":"rust-gix-fs","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-gix-fs?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.12.1-1","0.16.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"librust-gix-fs-dev","binary_version":"0.16.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-123532.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
