CVE-2025-2045 Overview
CVE-2025-2045 is an improper authorization vulnerability in GitLab Enterprise Edition (EE). The flaw allows users with limited permissions to access potentially sensitive project analytics data. The issue affects GitLab EE versions 17.7 prior to 17.7.6, 17.8 prior to 17.8.4, and 17.9 prior to 17.9.1. The vulnerability is tracked under CWE-863: Incorrect Authorization.
Exploitation requires an authenticated account with low privileges and no user interaction. The impact is limited to confidentiality of analytics data, with no integrity or availability effects.
Critical Impact
Low-privileged authenticated users can view project analytics data they should not have access to, exposing metrics that may reveal internal development activity and sensitive project telemetry.
Affected Products
- GitLab Enterprise Edition 17.7 through 17.7.5
- GitLab Enterprise Edition 17.8 through 17.8.3
- GitLab Enterprise Edition 17.9.0

Technical Details for CVE-2025-2045
Vulnerability Analysis
The vulnerability is a broken access control issue in GitLab EE's project analytics feature. GitLab enforces role-based access control through permission checks tied to project membership and role assignments such as Guest, Reporter, Developer, Maintainer, and Owner. The affected code path does not correctly validate whether the requesting user holds the role required to view analytics data.
As a result, users with limited permissions receive responses containing analytics telemetry intended for higher-privileged roles. The exposure is restricted to confidentiality of analytics content. Attackers cannot modify data or disrupt service through this flaw alone.
The underlying weakness class, CWE-863, applies when an application performs an authorization check but uses incorrect logic or the wrong permission scope. According to the GitLab issue tracker and the HackerOne report, the flaw was reported through GitLab's coordinated disclosure program.
Root Cause
The root cause is an incorrect authorization check in the analytics endpoint of GitLab EE. The permission policy tied to the analytics resource does not enforce the minimum role required to read project analytics. Users below the intended role threshold pass the check and receive the data.
Attack Vector
An authenticated attacker with any low-privileged role in a target project sends a request to the vulnerable analytics endpoint over the network. The server returns analytics data without enforcing the correct role gate. No user interaction, elevated privileges, or chained vulnerabilities are required.
No verified proof-of-concept code is publicly available. Refer to the GitLab Issue #512050 and HackerOne Report #2921111 for coordinated disclosure details.
Detection Methods for CVE-2025-2045
Indicators of Compromise
- Requests to project analytics API endpoints from accounts holding Guest or other low-privileged roles.
- Analytics-related HTTP 200 responses in production_json.log for users who should not have analytics visibility.
- Unusual spikes in analytics page views from accounts with limited project membership.
Detection Strategies
- Correlate GitLab audit events with user role assignments to flag analytics access by users below Reporter role.
- Query production_json.log and api_json.log for requests to /analytics routes and cross-reference with project membership data.
- Baseline typical analytics consumers per project and alert on new low-privileged accounts accessing those endpoints.
Monitoring Recommendations
- Forward GitLab audit and application logs to a centralized SIEM for role-versus-access correlation.
- Enable and retain GitLab audit events for project membership, role changes, and analytics feature access.
- Review GitLab's built-in audit event stream for anomalous access patterns to project analytics dashboards.
How to Mitigate CVE-2025-2045
Immediate Actions Required
- Upgrade GitLab EE to version 17.7.6, 17.8.4, or 17.9.1 or later as documented by GitLab.
- Inventory all self-managed GitLab EE instances and confirm running versions against the fixed releases.
- Audit project membership and remove unnecessary low-privileged accounts from sensitive projects until patching completes.
Patch Information
GitLab has released fixed versions 17.7.6, 17.8.4, and 17.9.1 that address CVE-2025-2045. Self-managed customers should follow the standard upgrade procedure documented by GitLab. GitLab.com SaaS tenants are patched by GitLab. Refer to GitLab Issue #512050 for coordinated disclosure context.
Workarounds
- Restrict project membership to trusted users until the upgrade is applied.
- Disable or hide the project analytics feature for exposed projects where feasible.
- Move sensitive projects behind stricter visibility settings such as Private until patching is complete.
# Verify installed GitLab version on a self-managed instance
sudo gitlab-rake gitlab:env:info | grep -i version
# Upgrade example on Debian/Ubuntu after configuring the GitLab EE repository
sudo apt-get update
sudo apt-get install gitlab-ee=17.9.1-ee.0
