GitLab has remediated a low-severity vulnerability identified as CVE-2025-9957. This issue impacts GitLab CE/EE across several versions, specifically all versions from 11.2 before 18.9.6, 18.10 before 18.10.4, and 18.11 before 18.11.1. The vulnerability allows an authenticated user with project owner permissions to potentially bypass group fork prevention settings due to improper authorization checks. This flaw could lead to unintended exposure of sensitive project configurations or unauthorized modifications.
The CVSS score for this vulnerability is 2.7, indicating a low severity level. Despite the low score, the risk to organizations includes the potential for project owners to inadvertently expose project data or configurations. Therefore, it is essential for organizations utilizing affected versions to prioritize remediation efforts as soon as possible.
Currently, there is no known exploit for this vulnerability, and it has not been found in public exploit databases. This absence of active exploitation reduces immediate risk; however, organizations should remain vigilant and monitor for any updates or patches released by GitLab.
Organizations should prioritize patching immediately to mitigate any risk stemming from this vulnerability. The urgency for defenders is heightened given the potential for improper access controls in GitLab environments.
Vulnerability Details
The vulnerability allows an authenticated user with project owner permissions to bypass group fork prevention settings under certain conditions. The official CVE description states that this results from improper authorization checks within GitLab. The affected systems include GitLab CE and EE for versions prior to the latest security updates.
The CVSS score of 2.7 reflects a low severity rating, indicating that while the vulnerability may not pose an immediate threat, it is still a concern that requires attention. The CWE classification associated with this issue is CWE-863, indicating a problem related to improper authorization.
Technical Analysis
The root cause of this vulnerability lies in improper authorization checks that allow project owners to bypass established group fork prevention settings. The attack vector for this vulnerability is classified as network-based, with a low attack complexity due to the nature of the authorization flaw. Privileges required are high, as an attacker must possess project owner permissions to exploit the vulnerability.
User interaction is not required for this vulnerability to be exploited. The impact on confidentiality is rated as none, while the integrity impact is low, indicating that unauthorized modifications could occur. Availability impact is also rated as none, meaning the vulnerability does not disrupt service availability.
Risk & Impact Analysis
Real-world deployment of this vulnerability presents a risk where authenticated users could unintentionally expose sensitive information or configurations. The blast radius potential is limited to the affected systems, primarily impacting organizations that utilize GitLab CE and EE versions mentioned earlier.
Organizations should assess their usage of GitLab and ensure they are running updated versions. Given the low CVSS score, organizations may schedule remediation within their regular patch cycles; however, vigilance is advised to prevent possible exploitation.
