How to Fix CVE-2024-53263

To remediate this vulnerability, upgrade all affected Github.com/git lfs/git lfs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/git-lfs/git-lfs fixed: Latest secure release
Upgrade github.com/git-lfs/git-lfs to Latest secure release
github.com/git-lfs/git-lfs/v3 fixed: 3.6.1
Upgrade github.com/git-lfs/git-lfs/v3 to 3.6.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/git-lfs/git-lfs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-53263, inspect your project dependencies for Github.com/git lfs/git lfs:

inspect dependencies for github.com/git-lfs/git-lfs

Analyze the terminal output to locate any version of Github.com/git lfs/git lfs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-436: Interpretation Conflict, where product a handles inputs or steps differently than product b, which causes a to perform incorrect actions based on its perception of b's state. In Github.com/git lfs/git lfs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact When Git LFS requests credentials from Git for a remote host, it passes portions of the host's URL to the `git-credential(1)` command without checking for embedded line-ending control characters, and then sends any credentials it receives back from the Git credential helper to the remote host. By inserting URL-encoded control characters such as line feed (LF) or carriage return (CR) characters into the URL, an attacker may be able to retrieve a user's Git credentials. ### Patches This problem exists in all previous versions and is patched in v3.6.1. All users should upgrade to v3.6.1. ### Workarounds There are no workarounds known at this time. ### References * https://github.com/git-lfs/git-lfs/security/advisories/GHSA-q6r2-x2cc-vrp7 * https://nvd.nist.gov/vuln/detail/CVE-2024-53263 * https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-53263 * https://github.com/git-lfs/git-lfs/releases/tag/v3.6.1 * [git-lfs/git-lfs@0345b6f816](https://github.com/git-lfs/git-lfs/commit/0345b6f816e611d050c0df67b61f0022916a1c90) ### For more information If you have any questions or comments about this advisory: * For general questions, start a discussion in the Git LFS [discussion forum](https://github.com/git-lfs/git-lfs/discussions). * For reports of additional vulnerabilities, please follow the Git LFS [security reporting policy](https://github.com/git-lfs/git-lfs/blob/main/SECURITY.md).
