The Reviso Exporter for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the disconnect_callback() function in versions up to, and including, 1.2.3. The function is registered to the 'wp_ajax_wcefr-disconnect' AJAX action and unconditionally calls delete_option('wcefr-agt'), which removes the Reviso Agreement Grant Token used to authenticate API calls. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete the plugin's stored Agreement Grant Token, breaking the connection between WooCommerce and the Reviso service.
AnalysisAI
Unauthorized token deletion in the Reviso Exporter for WooCommerce WordPress plugin (≤1.2.3) allows any authenticated subscriber-level user to permanently delete the plugin's stored Reviso Agreement Grant Token via an unprotected AJAX action, severing the WooCommerce-to-Reviso accounting service integration. The vulnerability stems from the disconnect_callback() function registered to wp_ajax_wcefr-disconnect performing no capability check and no nonce verification, meaning any logged-in WordPress user - including those with the lowest default role - can trigger it. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress session at Subscriber role or above - the lowest non-anonymous role. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) reflects the low-privilege, network-exploitable nature of this flaw but may underweight the service-availability disruption: deleting the Reviso token breaks the live accounting integration until an admin manually reconnects, which is a tangible operational impact not captured by A:N. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: version 1.2.4. … Detailed patch versions, workarounds, and compensating controls in full report. |
