Detailsinfo

A vulnerability was found in GitLab Enterprise Edition up to 18.0.5/18.1.3/18.2.1. It has been rated as problematic. This issue affects some unknown functionality of the component IP Restrictions Handler. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. Using CWE to declare the problem leads to CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. Impacted is confidentiality. The summary by CVE is:

An improper access control in Gitlab EE affecting all versions from 12.0 prior to 18.0.6, 18.1 prior to 18.1.4, and 18.2 prior to 18.2.2 that under certain conditions could have allowed users to view assigned issues from restricted groups by bypassing IP restrictions.

The weakness was released by rogerace as 525515. The advisory is shared at gitlab.com. The identification of this vulnerability is CVE-2025-2498 since 03/18/2025. The exploitation is known to be difficult. The attack may be initiated remotely. Neither technical details nor an exploit are publicly available.

Upgrading to version 18.0.6, 18.1.4 or 18.2.2 eliminates this vulnerability.
