Last modified

CVE-2026-97626 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
