MEDIUM CVE-2026-14603 Deferred

WowOptin public recipe route can disable every opt-in

WowOptin before 1.4.38 exposes GET /wp-json/optn/v1/recipes/ with permission_callback set to __return_true. The unauthenticated request's disable_others and status values reach handle_activate_recipe() and Db::activate_recipe(), allowing an attacker to disable every existing opt-in form and insert an enabled vendor-template row into the database.

Weakness
CWE-284 — Improper Access Control

This CVE was published Jul 24, 2026 and is one of 4 known issues for this plugin.

What to do

Update, patch or deactivate.

Update WowOptin to 1.4.38 or later. The application fix replaces __return_true on the recipe route with the same current_user_can(OPTN_MIN_CAPABILITY) check used by the plugin's other administrative routes.

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.
