ProfileGrid lets Subscribers overwrite premium license settings
ProfileGrid before 5.9.9.7 exposes the pg_activate_license and pg_deactivate_license AJAX actions without a capability check. Their nonce is localized into wp-admin for any logged-in user, so a Subscriber can submit attacker-controlled pg_license, pg_item_id and pg_item_key values and overwrite or create the plugin's namespaced license options.

- Jul 24, 2026
- Weakness
- CWE-862 — Missing Authorization
This CVE was published Jul 24, 2026 and is one of 55 known issues for this plugin.
Update, patch or deactivate.
Update ProfileGrid to 5.9.9.7 or later. A source backport should require manage_options before either license action, then verify the action-specific nonce and allowlist known item keys.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The ProfileGrid WordPress plugin before 5.9.9.7 does not perform a capability check on its license management actions, relying only on a nonce that is exposed to any logged-in user, allowing authenticated users with Subscriber-level access and above to overwrite the site's premium license settings.
