CVE-2025-0376 is a high-severity cross-site scripting (XSS) vulnerability impacting GitLab Community Edition (CE) and Enterprise Edition (EE). This vulnerability allows attackers to execute unauthorized actions via a change page. It affects all GitLab versions from 13.3 prior to 17.6.5, 17.7 prior to 17.7.4, and 17.8 prior to 17.8.2. The potential for exploitation raises significant security concerns for organizations using GitLab.
With a CVSS score of 8.7, this vulnerability is classified as high severity. The risk to organizations includes unauthorized actions that can compromise sensitive data and disrupt operations. Organizations should prioritize patching immediately to mitigate this vulnerability.
As of now, there are no known public exploits associated with this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential risk necessitates vigilance as attackers may leverage this vulnerability.
Organizations using affected versions of GitLab should address this vulnerability in their priority patch cycle. Staying informed on security updates and implementing necessary patches is critical to safeguarding against potential threats.
Vulnerability Details
The vulnerability enables attackers to exploit it through unauthorized actions on the GitLab change page. The affected products include both GitLab CE and EE, across multiple versions. The vulnerability has been classified under CWE-79, indicative of improper neutralization of input during web page generation.
The official CVSS score provided by GitLab indicates a base score of 8.7, reflecting high severity, with the following metrics: attack vector is network, attack complexity is low, privileges required are low, user interaction is required, and confidentiality and integrity impacts are both rated high.
The vulnerability was published on February 12, 2025, and has been analyzed for its impacts on security protocols and deployment processes.
Technical Analysis
The root cause of CVE-2025-0376 lies in the improper handling of user input in GitLab's change page functionality. This oversight allows attackers to inject malicious scripts that could be executed in the context of other users' sessions.
The attack vector is through the network, which means that the vulnerability can be exploited remotely without physical access to the systems. The attack complexity is low, indicating that the vulnerability can be exploited easily without significant technical skills. While the attacker requires low privileges, user interaction is necessary to trigger the exploit.
The impacts of this vulnerability are significant, with high confidentiality and integrity impact scores indicating that sensitive data could be compromised. Availability is not impacted, which means that the system remains operational, but the integrity of the data could be at risk.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-0376 is critical, given the potential for unauthorized access to sensitive data and disruption of services. The blast radius for organizations utilizing GitLab is extensive, as many users could be affected by the exploitation of this vulnerability.
Organizations must recognize the urgency of this vulnerability based on its CVSS score of 8.7. Immediate action is required to patch affected systems and mitigate any potential exploitation risks. Regular monitoring and adherence to security practices are essential to prevent any future occurrences.
