CVE intelligence and bounded remediation
CVE-2024-7493 — The WPCOM Member plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.5.2.1
Critical
CVSS 9.8
The WPCOM Member plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.5.2.1. This is due to the plugin allowing arbitrary data to be passed to wp_insert_user() during registration. This makes it possible for unauthenticated attackers to update their role to that of an administrator during registration.

Matched remediation archetype
Privilege escalation and unsafe privilege management
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
- Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
- Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.
Remediate safely
- Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
- Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
- Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
