CVE-2026-73126: Gitea private workflow badge token scope bypass

Severity: medium (CVSS 4.3 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 0.3% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2026-10-14 · updated 2026-10-14
Weakness: CWE-863

Description

Gitea's Actions workflow status badge endpoint does not enforce repository-read scope or the public-only restriction on the token authenticating the request. A token lacking read:repository, or restricted to public repositories, can retrieve the latest workflow status of a private repository accessible to its owner. This discloses private workflow status beyond the token's intended delegated permissions.

Affected products
