CVE-2026-97626

Requesting a user or organization profile page (GET /{username}) with an Accept: application/rss+xml or Accept: application/atom+xml header returned the owner's activity feed without the visibility check that the profile page and the .rss and .atom routes apply. Anonymous users, restricted users and non-members could confirm the existence of limited or private users and private organizations and read their profile details and public activity, also when [other] ENABLE FEED was disabled. Activity in private repositories was not included.
