CVE-2026-3228 | BDVDB-2026-319480 Detail
nextscriptsNextScripts: Social Networks Auto-Poster
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact none. Attack vector: network.
Weaknesses#
- CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
