CVE-2026-92243: Ivory Search WordPress Search Plugin reflected XSS via search parameter

CVE-2026-92243 · Severity: medium · CVSS 6.1 · Published 2026-10-03

The Ivory Search WordPress Search Plugin is vulnerable to reflected cross-site scripting (XSS) through the search parameter, allowing unauthenticated attackers to inject malicious scripts into search pages. When a user visits an infected page with the search terms highlighted, their browser executes the attacker's code, potentially stealing session cookies, redirecting to phishing sites, or stealing sensitive information. The attack requires the site administrator to have enabled the "Highlight Search Terms" feature and the malicious search query must return at least one result.

Vendors: Automattic.

Technical details

The plugin fails to properly sanitize and escape the 's' search parameter before outputting it to the page, enabling reflected XSS. An unauthenticated attacker can craft a malicious URL with JavaScript in the search parameter that executes in the victim's browser. Successful exploitation requires two preconditions: the "Highlight Search Terms" option must be enabled by an administrator, and the search query must return at least one post result to trigger the vulnerable code path.
