Technical details
The get-view-only-bundle RPC endpoint failed to filter share-link tokens based on the caller's authentication scope, returning all share links for a file regardless of which token was used. An attacker with a restrictive share link could enumerate other links' secret IDs and permissions, then use more permissive tokens to bypass intended access restrictions. The fix filters the response to include only the share link used for authentication when the caller is an anonymous share-link holder.
