This is due to the plugin registering the easy_invoice_accept_quote and easy_invoice_decline_quote AJAX actions via wp_ajax_nopriv_ hooks and relying solely on a quote-scoped nonce that is rendered into the publicly accessible single quote template, combined with an ownership check that is gated behind an off-by-default Pro option (easy_invoice_pro_restrict_quote_to_client). This makes it possible for unauthenticated attackers to accept or decline arbitrary published quotes — and, depending on the configured accept action, automatically convert them into invoices (and even email them to the client) — by harvesting the per-quote nonce from the public quote page and submitting it to admin-ajax."}],"title":"Easy Invoice <= 2.1.19 - Unauthenticated Arbitrary Quote Accept/Decline and Invoice Creation via easy_invoice_accept_quote / easy_invoice_decline_quote AJAX Actions","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/dab1c93d-e83c-4d38-be80-56d8e32f1894?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.2.0/includes/Controllers/QuoteController.php#L1022"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.2.0/includes/Controllers/QuoteController.php#L1453"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.2.0/includes/Controllers/QuoteController.php#L88"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.2.0/templates/quotes/single.php#L1462"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.1.12/includes/Controllers/QuoteController.php#L1022"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.1.12/includes/Controllers/QuoteController.php#L1453"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.1.12/includes/Controllers/QuoteController.php#L88"},{"url":"https://plugins.trac.wordpress.org/browser/easy-invoice/tags/2.1.12/templates/quotes/single.php#L1462"},{"url":"https://plugins.trac.wordpress.org/changeset/3517910/easy-invoice/trunk/includes/Controllers/QuoteController.php"}],"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":"PeterPatter"}],"timeline":[{"time":"2026-07-08T20:50:02.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-09T13:51:54.715152Z","id":"CVE-2026-9021","options":[{"Exploitation":"none"},{"Automatable":"no"},{"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":"2026-07-09T13:52:00.900Z"}}]}}
