An issue has been discovered in GitLab EE/CE affecting all versions starting from 8.0 before 16.4. The product did not sufficiently warn about security implications of granting merge rights to protected branches.
The product’s intended functionality exposes information to certain actors in accordance with the developer’s security policy, but this information is regarded as sensitive according to the intended security policies of other stakeholders such as the product’s administrator, users, or others whose information is being processed.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Gitlab | Gitlab | 8.0.0 (including) | 16.4.0 (excluding) |
| Gitlab | Ubuntu | esm-apps/xenial | * |
When handling information, the developer must consider whether the information is regarded as sensitive by different stakeholders, such as users or administrators. Each stakeholder effectively has its own intended security policy that the product is expected to uphold. When a developer does not treat that information as sensitive, this can introduce a vulnerability that violates the expectations of the product’s users.
