{"id":"CVE-2026-6399","state":"PUBLISHED","title":"General Options <= 1.1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'ad_contact_number' Parameter","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 — a function that strips HTML tags but does not encode double-quote characters to their HTML entity equivalent (&quot;). 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 — 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.","publishedAt":"2026-05-20T01:25:54.983Z","updatedAt":"2026-05-20T13:02:41.740Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["yog2515 General Options"],"affected":[{"vendor":"yog2515","product":"General Options","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d29c69bb-4feb-477e-b18f-934ece21aff6?source=cve","https://plugins.trac.wordpress.org/browser/general-options/trunk/direct-main.php","https://plugins.trac.wordpress.org/browser/general-options/tags/1.1.0/direct-main.php","https://plugins.trac.wordpress.org/browser/general-options/trunk/direct-action.php","https://plugins.trac.wordpress.org/browser/general-options/tags/1.1.0/direct-action.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6399.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6399","state":"PUBLISHED","datePublished":"2026-05-20T01:25:54.983Z","dateUpdated":"2026-05-20T13:02:41.740Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-15T20:26:58.860Z"},"containers":{"cna":{"title":"General Options <= 1.1.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via 'ad_contact_number' Parameter","descriptions":[{"lang":"en","value":"The General Options plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.1.0.
