CVE-2026-114199
No CVSS score yet. EPSS 0.2% estimated probability of exploitation activity in the next 30 days.
`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.
