• Severity: medium (CVSS 6.5 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: 2026-10-18 · updated 2026-10-19
• Weakness: CWE-862

Description

Seven Gitea API routes under `/api/v1/users/{username}` (followers, following, following/{target}, starred, subscriptions, keys and gpg_keys) were registered without the `individualPermsChecker` middleware that enforces the visibility of the target user. An authenticated user could therefore read the followers, following list, starred and watched repositories and public SSH and GPG keys of a user with limited or private visibility, whom they could not otherwise see. The issue was fixed in 1.27.3 and 28.0.0 and disclosed with 28.2.0.

Affected products

• Gitea Open Source Git Server: through 1.27.2
