CVE, Research URL: CVE-2026-3228
Home page URL: Security reports for NextScripts: Social Networks Auto-Poster
Application: NextScripts: Social Networks Auto-Poster
Published on: Mar 10, 2026
Research Description: The NextScripts: Social Networks Auto-Poster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `[nxs_fbembed]` shortcode in all versions up to, and including, 4.4.6. This is due to insufficient input sanitization and output escaping on the `snapFB` post meta value. 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.
Affected versions: max 4.4.7.
Status: vulnerable
