General Options <= 1.1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'ad_contact_number' Parameter_CVE-2026-6399

{
    "lastseen": "",
    "description": "The General Options plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.1.0. This is due to the use of sanitize_text_field() for output escaping in the Contact Number (ad_contact_number) field \u2014 a function that strips HTML tags but does not encode double-quote characters to their HTML entity equivalent ("). When the stored value is echoed inside a double-quoted HTML attribute (value=\"...\"), an attacker-supplied double-quote character breaks out of the attribute context. Even with WordPress's wp_magic_quotes mechanism (which prefixes quotes with a backslash), the resulting \\\" sequence is NOT treated as an escaped quote by HTML parsers \u2014 the backslash is rendered as a literal character and the bare double-quote still closes the attribute. This makes it possible for authenticated attackers with Administrator-level access and above to inject arbitrary web scripts in the admin settings page that will execute whenever any administrator visits the General Options settings page.",
