CVE-2024-21532

Summary

CVE-2024-21532 is a new command injection vulnerability affecting all versions of the ggit package. The issue lies in the fetchTags(branch) API, which permits users to specify the branch to be fetched. Malicious users can exploit this vulnerability by injecting commands, which are then concatenated with git commands and executed using the unsafe exec() Node.js child process API. This combination allows attackers to execute arbitrary commands on the affected system, potentially leading to significant security risks. Users are strongly encouraged to update to the latest version of ggit as soon as possible to mitigate this threat.
