This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the plugin's API key stored in wp_options, modify invoice plugin settings, and alter WooCommerce tax rate data in the wp_woocommerce_tax_rates table.","publishedAt":"2026-07-10T09:32:42.851Z","updatedAt":"2026-07-10T14:03:50.477Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["saskaita123 Invoice123"],"affected":[{"vendor":"saskaita123","product":"Invoice123","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.7.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7d4e685a-0462-447f-a639-4f95d5aa27ab?source=cve","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.7.0/includes/pages/S123_InvoiceSettings.php#L26","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.7.0/includes/pages/S123_InvoiceSettings.php#L65","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.7.0/includes/pages/S123_ApiKey.php#L29","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.7.0/includes/pages/S123_InvoiceSettings.php#L18","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.7.0/includes/pages/S123_ApiKey.php#L21","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_InvoiceSettings.php#L26","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_InvoiceSettings.php#L65","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_ApiKey.php#L29","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_InvoiceSettings.php#L18","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_ApiKey.php#L21","https://plugins.trac.wordpress.org/changeset?reponame=&old=3594935%40saskaita123-lt&new=3594935%40saskaita123-lt"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:52.441Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/9xxx/CVE-2026-9857.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-9857","state":"PUBLISHED","datePublished":"2026-07-10T09:32:42.851Z","dateUpdated":"2026-07-10T14:03:50.477Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-28T15:53:49.759Z"},"containers":{"cna":{"title":"Invoice123 <= 1.7.0 - Missing Authorization to Authenticated (Subscriber+) Setting Modification via s123_submit_api_key & s123_submit_invoice_settings AJAX actions","descriptions":[{"lang":"en","value":"The Invoice123 plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.0.
