Description
REBUILD before 4.5.3 contains an authorization bypass vulnerability in FeedsListController fetchDetails and fetchComments that skips privilege filtering and FeedsHelper.checkReadable checks. Authenticated attackers can enumerate sequential IDs via the feeds-details and comments-list endpoints to read private or team-scoped feed content, images, attachments and comments.
