CVE-2026-7767 · Severity: medium · CVSS 5.8 · Published 2026-10-13

GitLab is a web-based platform for version control and CI/CD that many organizations use to manage their code and deployments. A vulnerability in GitLab's Kubernetes integration could allow an authenticated user who controls a Kubernetes agent to redirect authentication tokens to an unintended server through an open redirect flaw, potentially exposing sensitive credentials to attackers.

## Technical details

An open redirect vulnerability exists in GitLab's Kubernetes proxy due to improper redirect validation. An authenticated user controlling a Kubernetes agent can exploit this to redirect sensitive authentication tokens to an attacker-controlled server. The vulnerability affects multiple version lines and requires both authentication and control of a Kubernetes agent.

## Affected products

- GitLab GitLab CE 13.11 to 19.2.7, 19.3.0 to 19.3.4, 19.4.0 to 19.4.1
- GitLab GitLab EE 13.11 to 19.2.7, 19.3.0 to 19.3.4, 19.4.0 to 19.4.1
