CVE detail
CVE-2026-15100
The Post Grid Gutenberg Blocks – PostX plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'searchnoresult' Block Attribute in all versions up to, and including, 5.0.32 due to insufficient input sanitization and output escaping. 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. This is particularly concerning in a cross-privilege scenario where a Contributor creates a pending or draft post containing the malicious block attribute, which then executes arbitrary JavaScript in the browser session of an Editor or Administrator who previews that post.
