Newpost Catch plugin lets logged‑in users run scripts

CVE-2025-1406 · published 1 year ago
Summary

The Newpost Catch plugin for WordPress (versions up to 1.3.19) allows users who can log in with contributor rights or higher to place malicious code into pages via the npc shortcode. When other visitors view those pages, the hidden code runs in their browsers, potentially stealing data or hijacking sessions. Update the plugin to a patched version or remove the shortcode feature until a fix is applied.

Original advisory text
Newpost Catch <= 1.3.19 - Authenticated (Contributor+) Stored Cross-Site Scripting via npc Shortcode
The Newpost Catch plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's npc shortcode in all versions up to, and including, 1.3.19 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
