This is due to insufficient input sanitization on the public /wp-json/anycomment/v1/subscribe REST endpoint and missing output escaping in AnyCommentSubscriptionsTable::column_default(), which returns the stored email verbatim into an HTML <td> when the subscription's user_ID does not resolve to an existing WP_User. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the AnyComment → Subscriptions admin page.","state":0,"publishedAt":"2026-10-14T02:27:38.905+00:00","modifiedAt":"2026-10-14T14:19:27.126+00:00","affected":[{"ecosystem":"Vendor product","name":"AnyComment","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ateshabaev\",\n                    \"product\": \"AnyComment\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"0.3.6\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ce925d1c-2254-49ea-9fcf-e948813b3f2c?source=cve","https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Admin/Tables/AnyCommentSubscriptionsTable.php#L107","https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Rest/AnyCommentRestSubscriptions.php#L124","https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Rest/AnyCommentRestSubscriptions.php#L59","https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Models/AnyCommentSubscriptions.php#L311"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-103422","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-103422","identifiers":["CVE-2026-103422"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
