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.","severity":{"version":"3.1","score":6.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00264,"percentile":0.18364,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2026-03-21T03:27:09Z","modified":"2026-06-17T10:44:35Z","products":[{"vendor":"hoosierdragon","product":"text toggle"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/d7ac0683-120f-4e76-9d44-5ee1c789b2c8?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L116"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L116"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L119"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L119"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L108"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L108"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/trunk/avp-texttoggle.php#L72"},{"url":"https://plugins.trac.wordpress.org/browser/text-toggle/tags/1.1/avp-texttoggle.php#L72"},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-3997"},{"url":"https://github.com/advisories/GHSA-m3x9-6r4v-vvcw"}],"sources":{"cve":[{"id":"CVE-2026-3997","title":"Text Toggle \u003c= 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.
