Medium · 6.5 Public exploit CVE-2026-97859 EUVD-2026-103993

Gitea API disclosure of private user social graph, keys and stars

Published Oct 18, 2026 · Updated Oct 19, 2026 · Assigned by Gitea

Vendor: Gitea Product: Gitea

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.
