CVE-2026-78335 · Severity: medium · CVSS 4.2 · Published 2026-10-13

GitLab, a widely-used DevOps platform for source code management and CI/CD, contains an authorization flaw affecting how it validates project-scoped personal access tokens. An authenticated user with a limited token scoped to specific projects could bypass access controls to modify integrations belonging to groups outside the token's permitted scope, potentially exposing group configurations or integrations to unauthorized modification.

## How to fix

- Fixed in GitLab CE/EE 19.2.8, 19.3.5, 19.4.2

## Technical details

An incorrect authorization check in GitLab CE/EE allows an authenticated user holding a project-scoped fine-grained Personal Access Token to modify group integrations outside the token's intended scope. The vulnerability results from insufficient authorization validation in the integration management logic. A network-based attack requires prior authentication and affects versions 19.1–19.4.1.

## Affected products

- GitLab GitLab CE 19.1 before 19.2.8, 19.3 before 19.3.5, 19.4 before 19.4.2
- GitLab GitLab EE 19.1 before 19.2.8, 19.3 before 19.3.5, 19.4 before 19.4.2

## Timeline

- 2026-10-13: disclosed: Security advisory published
