What is CVE-2026-32631?
CVE-2026-32631 is a high-severity vulnerability in git-for-windows git, published on 15 Apr 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Git for Windows is the Windows port of Git. Versions prior to 2.53.0.windows.3 do not have protections that prevent attackers from obtaining a user's NTLM hash. The NTLM hash can be obtained by tricking users into cloning a malicious repository, or checking out a malicious branch, that accesses an attacker-controlled server. By default, NTLM authentication does not need any user interaction. By brute-forcing the NTLMv2 hash (which is expensive, but possible), credentials can be extracted. This issue has been fixed in version 2.53.0.windows.3.
