{"id":"CVE-2026-3997","state":"PUBLISHED","title":"Text Toggle <= 1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute","description":"The Text Toggle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' shortcode attribute of the [tt_part] and [tt] shortcodes in all versions up to and including 1.1. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. Specifically, in the avp_texttoggle_part_shortcode() function, the 'title' attribute is extracted from shortcode attributes and concatenated directly into HTML output without any escaping — both within an HTML attribute context (title=\"...\") on line 116 and in HTML content on line 119. While the 'class' attribute is properly validated using ctype_alnum(), the 'title' attribute has no sanitization whatsoever. An attacker can inject double-quote characters to break out of the title attribute and inject arbitrary HTML attributes including event handlers. 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":"2026-03-21T03:27:09.049Z","updatedAt":"2026-04-08T17:26:38.506Z","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":["hoosierdragon Text Toggle"],"affected":[{"vendor":"hoosierdragon","product":"Text Toggle","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d7ac0683-120f-4e76-9d44-5ee1c789b2c8?source=cve","https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L116","https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L116","https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L119","https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L119","https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L108","https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L108","https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L72","https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L72"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3997.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3997","state":"PUBLISHED","datePublished":"2026-03-21T03:27:09.049Z","dateUpdated":"2026-04-08T17:26:38.506Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-11T17:06:39.345Z"},"containers":{"cna":{"title":"Text Toggle <= 1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'title' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Text Toggle plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' shortcode attribute of the [tt_part] and [tt] shortcodes in all versions up to and including 1.1.
