Description
rssant 1.9.0 through 1.9.1 contains an authorization bypass vulnerability that allows unauthenticated attackers to read stories from unpublished feeds through the anonymous publish.story_get endpoint. Because UnionStory.get_by_feed_offset ignores the only_publish flag, attackers can enumerate feed IDs and offsets to retrieve private feed stories.
