Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe Simple User Registration WordPress plugin (versions <= 6.8) by N-Media contains an Incorrect Privilege Assignment vulnerability that allows authenticated users to escalate their privileges beyond what their assigned role should permit. This privilege escalation flaw likely stems from improper validation of user roles or capabilities during the registration or user management process, enabling lower-privileged users to gain administrative or higher-level access.
