Cloudreve before 4.16.1 Authentication Bypass via Cached Context Hint
Cloudreve before 4.16.1 fails to revalidate share access when restoring cached navigator state from a context_hint UUID. Attackers who previously had valid share access can replay the cached hint to generate signed file URLs for up to 300 seconds after the share is deleted, expires, or reaches zero remaining downloads.
