CVE-2026-24059: Gitea runner registration-token GET endpoint performs a write under a read-only token scope

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-13 · updated 2026-08-26
• Weakness: CWE-269

Description

The GET /api/v1/user/actions/runners/registration-token endpoint (and its owner- and repository-level equivalents) creates a new runner registration token if none exists, yet the API scope middleware classifies it as read-only because it is a GET request. A holder of a leaked read:user-scoped token can therefore mint a registration token and register a malicious Actions runner that executes workflow jobs with access to repository secrets and source code.
