Description
OmniRoute 3.8.50 before 3.8.52 contains a missing authentication vulnerability that allows unauthenticated attackers to issue sync tokens via POST /api/sync/tokens when requireLogin is disabled. Attackers can use the issued token against GET /api/sync/bundle to retrieve decrypted provider credentials and plaintext API keys, with tokens persisting after login is re-enabled.
