Summary:

Several security issues were fixed in Git LFS.

Software Description:
- git-lfs: Command line extension and spec for managing large files with Git

Details:

Ryota K discovered that Git LFS may leak login credentials in certain
instances due to failing to check for URL-encoded characters. An
attacker could possibly use this issue to learn sensitive information.
(CVE-2024-53263)

It was discovered that Git LFS could have its git lfs checkout and
git lfs pull commands abused to write to any file on a user's
system. An attacker could possibly use this issue to execute arbitrary
code. This issue was only addressed in Ubuntu 24.04 LTS and
Ubuntu 25.10. (CVE-2025-26625)
