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-284

Description

Gitea's repository markup endpoint resolves same-repository pull request references without enforcing the viewer's Pull Requests permission. A member with only Wiki access to a private repository can submit a markup preview request and retrieve a private pull request's title and state icon despite lacking Issues and Pull Requests access. This exposes pull request metadata across repository unit permissions.

Affected products

Gitea Open Source Git Server: through 1.27.2
