{"id":"CVE-2026-4082","state":"PUBLISHED","title":"ER Swiffy Insert <= 1.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The ER Swiffy Insert plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [swiffy] shortcode in all versions up to and including 1.0.0. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes ('n', 'w', 'h'). These attributes are extracted using extract() and directly interpolated into the HTML output without any escaping such as esc_attr(). This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-04-22T07:45:30.326Z","updatedAt":"2026-04-22T13:06:19.502Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["erithq ER Swiffy Insert"],"affected":[{"vendor":"erithq","product":"ER Swiffy Insert","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/074d9712-9b26-47da-9e24-49854fd7257c?source=cve","https://plugins.trac.wordpress.org/browser/er-swiffy-insert/trunk/er-swiffy-insert.php#L56","https://plugins.trac.wordpress.org/browser/er-swiffy-insert/tags/1.0.0/er-swiffy-insert.php#L56","https://plugins.trac.wordpress.org/browser/er-swiffy-insert/trunk/er-swiffy-insert.php#L49","https://plugins.trac.wordpress.org/browser/er-swiffy-insert/tags/1.0.0/er-swiffy-insert.php#L49"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4082.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4082","state":"PUBLISHED","datePublished":"2026-04-22T07:45:30.326Z","dateUpdated":"2026-04-22T13:06:19.502Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T20:46:40.814Z"},"containers":{"cna":{"title":"ER Swiffy Insert <= 1.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The ER Swiffy Insert plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [swiffy] shortcode in all versions up to and including 1.0.0.
