CVE-2023-3713Network attack vector

Subscriber-to-Administrator escalation via unchecked option writes

Published Jul 18, 2023 · Updated Apr 8, 2026

Missing authorization in ProfileGrid 5.5.1 and earlier allows remote authenticated users to overwrite WordPress site options. The profile_magic_check_smtp_connection handler accepts attacker-controlled SMTP-setting data and writes it into site options without verifying the caller's capability. Subscriber-level access is sufficient, and arbitrary option changes can elevate the account to administrative privileges.
