CVE-2025-4391

Name of the Vulnerable Software and Affected Versions: The Echo RSS Feed Post Generator plugin for WordPress versions up to, and including, 5.4.8.1

Description: The issue is related to arbitrary file uploads due to missing file type validation in the echo generate featured image() function. This allows unauthenticated attackers to upload arbitrary files on the affected site's server, potentially making remote code execution possible.

Recommendations: For versions up to, and including, 5.4.8.1, consider disabling the echo generate featured image() function until a patch is available to prevent arbitrary file uploads. Restrict access to file upload functionality to minimize the risk of exploitation.
