An issue was discovered in GitLab CE/EE affecting all versions starting from 17.4 prior to 17.5.5, starting from 17.6 prior to 17.6.3, and starting from 17.7 prior to 17.7.1. Under certain conditions, access tokens may have been logged when API requests were made in a specific manner. This vulnerability allows unauthorized access to sensitive data, thereby posing a risk to organizations using affected versions.
The CVSS score for this vulnerability is 6.5, classified as medium severity. This rating indicates potential risk, as attackers may leverage this vulnerability to gain access to sensitive information, including access tokens.
Organizations should prioritize patching immediately. The potential for exposure of access tokens could lead to unauthorized actions taken by malicious actors, thereby increasing the overall attack surface.
As of now, there are no known exploits in the wild for this vulnerability, but the risk remains significant due to the nature of the issue. GitLab has addressed this in their latest patch releases, and organizations should apply these updates promptly.
The vulnerability was published on January 8, 2025, and the last modification was on July 11, 2025. It is crucial for organizations to remain vigilant and monitor their systems for any signs of exploitation.
Vulnerability Details
CVE-2025-0194 is categorized under CWE-538, indicating that sensitive information is logged in an insecure manner. The attack vector for this vulnerability is network-based, and it has low attack complexity, requiring high privileges to exploit.
The vulnerability impacts GitLab CE/EE installations, specifically versions starting from 17.4 prior to 17.5.5, 17.6 prior to 17.6.3, and 17.7 prior to 17.7.1. Organizations using these versions should ensure they upgrade to the latest available patches.
Technical Analysis
The root cause of this vulnerability stems from improper logging of access tokens during API requests. Under certain scenarios, these tokens may be captured and stored in logs, which can be accessed by unauthorized users.
The attack vector is primarily network-based, allowing potential attackers to intercept API requests and exploit this logging issue. The attack complexity is considered low due to the straightforward nature of the exploit, while high privileges are required to access the logged tokens.
User interaction is not required for the exploitation of this vulnerability. Confidentiality and integrity impacts are both rated as high, while availability is not affected.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data through logged access tokens. The potential for attackers to exploit this vulnerability increases the overall risk profile for organizations using affected versions of GitLab.
The blast radius is significant, as any organization utilizing the impacted versions may face data leakage and subsequent attacks stemming from unauthorized access to sensitive tokens. Organizations should assess their deployment environments and implement the necessary patches to mitigate this risk.
Given the medium severity rating and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle to ensure continued security and compliance.
