Plataformatec

Plataformatec maintains a narrow set of Ruby authentication and form-handling libraries, Devise and Simple Form, that are embedded across many Rails applications and web services. The recurring vulnerability signal centers on input-validation and authentication-control weaknesses characteristic of libraries sitting at the boundary between user input and credential handling, including improper input validation, excessive authentication attempts, and race conditions in state-dependent logic. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
