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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_ApiKey.php#L21","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_InvoiceSettings.php#L26","https://plugins.trac.wordpress.org/browser/saskaita123-lt/tags/1.6.8/includes/pages/S123_InvoiceSettings.php#L65"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-9857","score":0.00473,"percentile":0.40883,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
