GP Unique ID < 1.5.6 - Unauthenticated Form Submission Unique ID Modification

Description The plugin is vulnerable to Unique ID Modification due to insufficient input validation. This makes it possible for unauthenticated attackers to tamper with the generation of a unique ID on a form submission and replace the generated unique ID with a user-controlled one, leading to a loss of integrity in cases where the ID’s uniqueness is relied upon in a security-specific context.
