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 contributor-level access and above, to overwrite plugin mail settings (from name and from email address), create audience lists, insert arbitrary contacts into those lists, create and overwrite newsletter broadcasts and post notifications, add workflows, and queue and dispatch mass email to arbitrary recipients.","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/email-subscribers/tags/5.9.21/lite/admin/class-email-subscribers-admin.php#L216","https://plugins.trac.wordpress.org/browser/email-subscribers/tags/5.9.21/lite/admin/class-ig-es-onboarding.php#L171","https://plugins.trac.wordpress.org/browser/email-subscribers/tags/5.9.21/lite/includes/class-email-subscribers-activator.php#L66","https://plugins.trac.wordpress.org/browser/email-subscribers/tags/5.9.21/lite/includes/classes/class-es-newsletters.php#L717","https://plugins.trac.wordpress.org/browser/email-subscribers/tags/5.9.21/lite/includes/workflows/admin/class-es-workflow-admin-edit.php#L74"],"products":[],"source":"nvd","synced_at":"2026-10-28T01:46:17.796035460+00:00"},"epss":{"cve":"CVE-2026-11592","score":0.00473,"percentile":0.40689,"date":"2026-10-27"},"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).
