{"schema":"threatline.record/2","record":{"id":"CVE-2026-103422","aliases":[],"summary":"AnyComment <= 0.3.6 - Unauthenticated Stored Cross-Site Scripting via 'email' Parameter","details":"The AnyComment plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email' parameter in versions up to, and including, 0.3.6. 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.","categories":["Unclassified"],"product":"AnyComment","vendor":"ateshabaev","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103422","source_modified_at":"2026-10-14T14:19:27.126Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"AnyComment","vendor":"ateshabaev","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.3.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00309,"percentile":0.2251,"score_date":"2026-10-23"},"published_at":"2026-10-14T02:27:38.905Z","modified_at":"2026-10-14T14:19:27.126Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-103422","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T14:19:27.126Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103422","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ce925d1c-2254-49ea-9fcf-e948813b3f2c?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Admin/Tables/AnyCommentSubscriptionsTable.php#L107"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Rest/AnyCommentRestSubscriptions.php#L124"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Rest/AnyCommentRestSubscriptions.php#L59"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/anycomment/tags/0.3.6/includes/Models/AnyCommentSubscriptions.php#L311"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T14:19:18.150325Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T14:19:27.126Z","content_hash":"79703c4b941aa13160755ebdf613f739d1fd198cc37e19db7d25e7cdb56ccb11"}}
