Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVE-2025-11148

High
9.8/10

Summary

All versions of the package check-branches are vulnerable to Command Injection check-branches is a command-line tool that is interacted with locally, or via CI, to confirm no conflicts exist in git branches. However, the library follows these conventions, which can be abused. First, It trusts branch names as they are (plain text). Second, It spawns git commands by concatenating user input. Since a branch name is potentially a user input - as users can create branches remotely via pull requests, or simply due to privileged access to a repository - it can effectively be abused to run any command.

CWE-78 - OS Command Injection

The OS command injection weakness (also known as shell injection) is a vulnerability which enables an attacker to run arbitrary OS commands on a server. This is done by modifying the intended downstream OS command and injecting arbitrary commands, enabling the execution of unauthorized OS commands. This has the potential to fully compromise the application along with all of its data, and, if the compromised process does not follow the principle of least privileges, it may compromise other parts of the hosting infrastructure as well. This weakness is listed as number ten in the 'CWE Top 25 Most Dangerous Software Weaknesses'.
