{"id":"CVE-2026-2422","state":"PUBLISHED","title":"WP Composer <= 1.0.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'pbwp_raw_shortcode' Shortcode","description":"The WP Composer – The Easiest Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pbwp_raw_shortcode' shortcode in all versions up to, and including, 1.0.5. This is due to the shortcode handler decoding Base64-encoded content and outputting it directly without any sanitization or escaping. 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. The Base64 encoding allows the payload to bypass WordPress's KSES content filtering at save time, since the encoded string contains no harmful HTML characters.","publishedAt":"2026-09-19T07:43:17.436Z","updatedAt":"2026-09-19T14:01:22.841Z","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":["ghozylab WP Composer – The Easiest Page Builder"],"affected":[{"vendor":"ghozylab","product":"WP Composer – The Easiest Page Builder","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.5","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/7e328f1d-687d-424f-aab7-343bcece90cd?source=cve","https://plugins.trac.wordpress.org/browser/page-builder-wp/tags/1.0.5/inc/global/wpc-helpers.php#L3578","https://plugins.trac.wordpress.org/browser/page-builder-wp/trunk/inc/global/wpc-helpers.php#L3578","https://plugins.trac.wordpress.org/changeset?reponame=&old=3482357%40page-builder-wp&new=3482357%40page-builder-wp"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2422.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2422","state":"PUBLISHED","datePublished":"2026-09-19T07:43:17.436Z","dateUpdated":"2026-09-19T14:01:22.841Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-12T20:16:29.208Z"},"containers":{"cna":{"title":"WP Composer <= 1.0.5 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'pbwp_raw_shortcode' Shortcode","descriptions":[{"lang":"en","value":"The WP Composer – The Easiest Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pbwp_raw_shortcode' shortcode in all versions up to, and including, 1.0.5.
