PasswordPusher before 2.11.1 contains a time-of-check-to-time-of-use race condition in view limit enforcement that allows unauthenticated attackers to bypass expire_after_views limits. Attackers can send concurrent requests to the show endpoint to access one-time secrets multiple times before the view count is incremented and the push expires.
