Description
Zed, a code editor, has an aribtrary code execution vulnerability in versions prior to 0
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A critical vulnerability has been identified in the Weblate localization tool, assigned CVE-2025-68398 with a CVSS score of 9.1. This flaw allows a remote attacker to overwrite Git configuration files, which can be leveraged to execute arbitrary code on the server. Successful exploitation could lead to a full system compromise, resulting in data theft, service disruption, and unauthorized access to the underlying infrastructure.
Vulnerability Details
CVE-ID: CVE-2025-68398
Affected Software: Weblate
Affected Versions: All versions prior to 5.15.1
Vulnerability:
The vulnerability exists due to improper validation of user-supplied input that affects the underlying Git repositories managed by Weblate. A remote attacker can craft a malicious request to overwrite the
.git/configfile for a specific project repository. By modifying this configuration, an attacker can manipulate Git's behavior, for example, by setting thecore.sshCommandorcore.hooksPathdirectives to point to a malicious script, leading to Remote Code Execution (RCE) when Weblate next performs a Git operation (e.g., a pull or push).Business Impact
This vulnerability is rated as critical severity with a CVSS score of 9.1. Successful exploitation could result in a complete compromise of the Weblate server, leading to significant business consequences. These include the theft of sensitive data such as source code, API keys, and user credentials; disruption of critical localization and development workflows; and reputational damage from a public security breach. A compromised server could also be used as a pivot point for attackers to move laterally within the organization's network, escalating the incident's impact.
Remediation Plan
Immediate Action:
Organizations must immediately upgrade all vulnerable Weblate instances to the patched version 5.15.1 or later. After applying the update, it is crucial to review access logs and Git repository configurations for any signs of compromise that may have occurred prior to patching, such as unexpected configuration changes or outbound connections.
Proactive Monitoring:
Implement enhanced monitoring for Weblate servers. Security teams should look for suspicious activity in application and system logs, such as unexpected processes being spawned by the Weblate service user. Monitor for unauthorized modifications to
.git/configfiles within project directories and scrutinize outbound network traffic from the Weblate server for connections to unknown or malicious IP addresses, which could indicate a reverse shell.Compensating Controls:
If immediate patching is not feasible, implement the following compensating controls to reduce risk:
.git/configfiles for any unauthorized changes and alert administrators.Exploitation Status
Public Exploit Available: False (as of Dec 18, 2025)
Analyst Notes:
As of December 18, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, due to the critical CVSS score and the high potential for developing a reliable Remote Code Execution exploit, it is highly probable that threat actors will reverse-engineer the patch and weaponize this vulnerability. Organizations should assume that exploitation is imminent.
Analyst Recommendation
Given the critical severity (CVSS 9.1) of this vulnerability, immediate action is required. We strongly recommend all organizations using affected versions of Weblate prioritize the deployment of the security patch (version 5.15.1 or later) to prevent a potential system compromise. While this CVE is not currently on the CISA KEV list, its characteristics make it a prime candidate for future inclusion. Proactive patching and monitoring are the most effective strategies to protect against this threat.
