{"id":"CVE-2026-5234","state":"PUBLISHED","title":"LatePoint <= 5.3.2 - Insecure Direct Object Reference to Unauthenticated Sensitive Financial Data Exposure via Sequential Invoice ID","description":"The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.3.2. The vulnerability exists because the OsStripeConnectController::create_payment_intent_for_transaction action is registered as a public action (no authentication required) and loads invoices by sequential integer invoice_id without any access_key or ownership verification. This is in contrast to other invoice-related actions (view_by_key, payment_form, summary_before_payment) in OsInvoicesController which properly require a cryptographic UUID access_key. This makes it possible for unauthenticated attackers to enumerate valid invoice IDs via an error message oracle, create unauthorized transaction intent records in the database containing sensitive financial data (invoice_id, order_id, customer_id, charge_amount), and on sites with Stripe Connect configured, the response also leaks Stripe payment_intent_client_secret tokens, transaction_intent_key values, and payment amounts for any invoice.","publishedAt":"2026-04-17T03:36:44.618Z","updatedAt":"2026-04-17T18:38:40.183Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["latepoint LatePoint – Calendar Booking Plugin for Appointments and Events"],"affected":[{"vendor":"latepoint","product":"LatePoint – Calendar Booking Plugin for Appointments and Events","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.3.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/afec4c8c-a18d-4907-8879-2412f8a1abed?source=cve","https://plugins.trac.wordpress.org/browser/latepoint/trunk/lib/controllers/stripe_connect_controller.php#L31","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.2.9/lib/controllers/stripe_connect_controller.php#L31","https://plugins.trac.wordpress.org/browser/latepoint/trunk/lib/controllers/stripe_connect_controller.php#L33","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.2.9/lib/controllers/stripe_connect_controller.php#L33","https://plugins.trac.wordpress.org/browser/latepoint/trunk/lib/controllers/stripe_connect_controller.php#L50","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.2.9/lib/controllers/stripe_connect_controller.php#L50","https://plugins.trac.wordpress.org/browser/latepoint/trunk/lib/controllers/stripe_connect_controller.php#L20","https://plugins.trac.wordpress.org/browser/latepoint/tags/5.2.9/lib/controllers/stripe_connect_controller.php#L20","https://plugins.trac.wordpress.org/changeset/3505127/latepoint/trunk/lib/controllers/stripe_connect_controller.php"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5234.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5234","state":"PUBLISHED","datePublished":"2026-04-17T03:36:44.618Z","dateUpdated":"2026-04-17T18:38:40.183Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-31T14:05:18.117Z"},"containers":{"cna":{"title":"LatePoint <= 5.3.2 - Insecure Direct Object Reference to Unauthenticated Sensitive Financial Data Exposure via Sequential Invoice ID","descriptions":[{"lang":"en","value":"The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.3.2.
