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 \u2014 and, depending on the configured accept action, automatically convert them into invoices (and even email them to the client) \u2014 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"}]}}}
