What is CVE-2026-14565?

The Advanced-Customized-Prompts WordPress plugin versions up to 1.0.1 is susceptible to a cross-site scripting vulnerability. This issue arises due to insufficient checks on user capabilities, ownership, and nonce verification before storing popup configurations. As a result, authenticated users, including subscribers, can insert malicious JavaScript that executes in the browsers of other users viewing affected products, potentially compromising their security. Immediate action should be taken to update to a secure version to mitigate this risk.
