Token disclosure via improperly validated proxy redirects
Published Oct 13, 2026 · Updated Oct 13, 2026
Open redirect in GitLab CE/EE's Kubernetes proxy allows remote authenticated users to disclose authentication tokens to another server. The proxy improperly validates redirects, sending sensitive tokens to an unintended destination; public material does not identify the faulty function or validation rule. Exploitation requires control of a Kubernetes agent and user interaction, with token disclosure rather than a demonstrated ability to modify data or interrupt service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=13.11 <19.2.8
- Affected versionversion=19.3 <19.3.5
- Affected versionversion=19.4 <19.4.2
