CVE-2026-73135: Gitea hidden-owner repository listing disclosure

Severity: medium (CVSS 5.3 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: 2026-10-14 · updated 2026-10-14
Weakness: CWE-200

Description

Gitea uses inconsistent repository visibility predicates, and the condition used by some repository-listing endpoints admits repositories whose owners are hidden from the viewer. Those listings disclose repository metadata even though direct routes correctly deny access with a 404 response. The issue exposes repository existence and listing information across the intended owner-visibility boundary.

Affected products
