Primarily affecting local Git repository clones where source and target repositories reside on the same disk, the risk arises only when the source repository is owned by a different, potentially untrusted user. This scenario necessitates specific conditions for exploitation, such as shared access to the disk among multiple users. Moreover, the impact is localized to the affected repositories and does not extend to the broader system or network. While the integrity of the target repository may be compromised if the untrusted user modifies linked files, the scope of influence is contained within the repository structure.", "threat_severity": "Low", "upstream_fix": "git 2.45.1, git 2.44.1, git 2.43.4, git 2.42.2, git 2.41.1, git 2.40.2, git 2.39.4"}
