Live › vulnerability › CVE-2026-119160
The Smart Post Gutenberg blocks plugin for WordPress does not sanitize the display_name parameter, letting a subscriber-level user store scripts. When a visitor clicks the attacker's entry in an Author Filter dropdown on a page with those blocks, the script runs in their browser.

Sites running the Smart Post plugin version 4.0.9 or earlier that have an Author Filter block on a page with a grid or live-filter block. Attackers need a subscriber-level account on the site, and visitors must click the injected author entry. Sites without the plugin or without those blocks are not affected.

The Smart Post – Post Grid, Post Carousel, Post Slider Gutenberg Blocks for Blog & News plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 4.0.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the victim page to contain an Author Filter block alongside a grid or live-filter block, and execution is triggered by a visitor clicking the attacker's author entry in the dropdown — a standard filter interaction requiring no elevated privileges from the victim.
