Unauthenticated privilege escalation
Published Sep 5, 2023 · Updated May 22, 2026
Privilege escalation in Unisign Bookreen before 3.0.0 allows remote attackers to gain elevated access through network requests. The public record identifies an incomplete list of disallowed inputs but does not disclose the affected endpoint, input field, or omitted values. No authentication or user interaction is required; successful exploitation can expose, alter, or interrupt application data and service operations.
