## What is CVE-2026-92243?

CVE-2026-92243 is a medium-severity cross-site scripting vulnerability in vinod-dalvi Ivory Search – WordPress Search Plugin, published on 3 Oct 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Ivory Search – WordPress Search Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 5.5.18 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the targeted search form has the 'Highlight Search Terms' option enabled by an administrator, and that the malicious search query returns at least one post result.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
