CVE-2026-114199 Details
Description
`GET /api/v1/users/{username}/heatmap` computed the contribution heatmap with the repository access of the token owner and ignored the public-only restriction of the access token, unlike the activity feed endpoints. A holder of a user's public-only token could read contribution counts and their 15-minute time buckets that stem from that user's activity in private repositories. Repository names and contents were not disclosed. For public-only tokens the heatmap now only counts activity visible to anonymous users.
A vulnerability in Gitea's contribution heatmap API endpoint allows public-only token holders to access private repository activity data. This issue arises because the heatmap calculation includes private contributions, contrary to the intended restriction for public-only tokens. The vulnerability is present in Gitea versions through 28.2.0 and has been patched in 28.3.0.
Users can upgrade to Gitea version 28.3.0, where this vulnerability has been fixed.
