This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to deactivate arbitrary member accounts by forging a charge.refunded webhook event containing a victim's subscription ID, setting the target member's account_state to 'inactive' and triggering cancellation hooks, transaction-record status changes, and cancellation notification emails. This vulnerability is exploitable only on installations where no Stripe webhook signing secret has been configured, which is the default out-of-the-box state; sites that have configured the stripe-webhook-signing-secret option are routed to the properly verified HMAC path and are not affected."}],"title":"Simple Membership <= 4.7.5 - Missing Authorization to Unauthenticated Arbitrary Member Account Deactivation via Forged Stripe 'charge.refunded' Webhook","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f91a7c3-ee0e-48e9-aa5f-dfc1160bbc09?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.4/ipn/swpm-stripe-webhook-handler.php#L297"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.4/ipn/swpm-stripe-webhook-handler.php#L71"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.4/classes/class.swpm-wp-loaded-tasks.php#L96"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.4/ipn/swpm_handle_subsc_ipn.php#L381"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.3/ipn/swpm-stripe-webhook-handler.php#L297"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.3/ipn/swpm-stripe-webhook-handler.php#L71"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.3/classes/class.swpm-wp-loaded-tasks.php#L96"},{"url":"https://plugins.trac.wordpress.org/browser/simple-membership/tags/4.7.3/ipn/swpm_handle_subsc_ipn.php#L381"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3573852%40simple-membership&new=3573852%40simple-membership&sfp_email=&sfph_mail="}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Nikita Fenko"}],"timeline":[{"time":"2026-06-12T14:23:09.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-06-17T16:52:42.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-18T13:21:36.202720Z","id":"CVE-2026-12093","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-18T13:53:39.765Z"}}]}}
