WordPress · Powerpress · CVE-2021-24123
Name of the Vulnerable Software and Affected Versions:
PowerPress WordPress plugin versions prior to 8.3.8
Description:
The issue allows high privilege accounts (admin+) to upload arbitrary files, such as php, due to a lack of verification for some uploaded feed images, like those from the Podcast Artwork section. This can lead to remote code execution (RCE).
Recommendations:
For versions prior to 8.3.8, update to version 8.3.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the Podcast Artwork section and limiting the types of files that can be uploaded by high privilege accounts.
