Overview<\/strong><\/p>\n

The reported vulnerability CVE-2025-30370 is associated with jupyterlab-git, a prominent extension for version control using Git in JupyterLab. It allows potential adversaries to inject malicious commands into the system. This vulnerability puts numerous systems at risk, potentially leading to unauthorized system control or data leakage. The severity and widespread usage of this extension make this vulnerability a significant concern for cybersecurity.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-30370
\nSeverity: High (7.4 CVSS Score)
\nAttack Vector: Local
\nPrivileges Required: User
\nUser Interaction: Required
\nImpact: Potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

jupyterlab-git | Versions prior to 0.51.1<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises from the ability to create a Git repository with a name including a shell command substitution string. If a user initiates JupyterLab in a parent directory of this maliciously named Git repository, opens it, and clicks “Git > Open Git Repository in Terminal” from the menu bar, the injected command is executed in the user’s shell without the user’s permission. This is because the terminal opened by jupyterlab-git executes any command substitution strings present in the directory name, leading to the command injection vulnerability.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

In this conceptual example, an adversary creates a Git repository with an embedded shell command:<\/p>\n

$ git init \"$(echo 'evilcommand')\"<\/code><\/pre>\n
When a user interacts with this repository through jupyterlab-git, the ‘evilcommand’ would be executed unknowingly.<\/p>\n
$ cd \"$(echo 'evilcommand')\"<\/code><\/pre>\n
Mitigation<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor patch by updating the jupyterlab-git extension to version 0.51.1 or later. As a temporary measure, using Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) could help detect and prevent exploitation attempts. Users should also inspect Git repository names for command substitution strings before interacting with them.<\/p>\n","protected":false},"excerpt":{"rendered":"
