CVE-2026-116289 Details
Description
Gitea did not reject personal access tokens restricted to public resources (`public-only`) on the organization Actions runner registration-token endpoint, and the runner registered with the resulting token was not limited to public repositories. Holding only such a token with `write:organization` that belongs to an owner of a public organization, an attacker could register an organization-level runner and receive jobs of the organization's private repositories that have Actions enabled, including the workflow content, Actions secrets and variables, and a task token with access to the private repository. The issue widens what the restricted token can reach; it gives nothing beyond what the owner's full account can already do.
A vulnerability in Gitea's Actions runner registration process allows for the unauthorized escalation of a public-only personal access token (PAT) scoped to 'write:organization'. This issue is present in Gitea versions through 28.2.0. When such a token is used to register an organization-level runner, the 'public-only' restriction is not enforced, enabling the runner to receive jobs from private repositories within the organization. As a result, an attacker could access private repository workflows, secrets, and a task token with repository access. This vulnerability exploits the token scope management, bypassing intended visibility restrictions and leading to unauthorized access to private resources and workflows.
Users can upgrade to Gitea version 28.3.0, where this vulnerability has been fixed.
