Introduction
Attackers can extract authentication credentials from public log files on WordPress sites running vulnerable versions of the CE21 Suite plugin. This exposure can lead to full administrative compromise if an administrator has ever used the plugin's authentication feature. The CE21 Suite plugin is a niche integration tool for connecting WordPress with CE21's platform services. As of its removal from the WordPress.org repository, it had a small but nonzero installed base, and its vulnerabilities have been the subject of multiple CVEs.
About CE21 Suite: CE21, LLC develops plugins for integrating CE21 platform features into WordPress. The plugin is not widely deployed, with only about 30 active installations at the time of its removal, but it has been the subject of several critical vulnerabilities.
Technical Information
CVE-2025-11008 is a sensitive information exposure vulnerability in the CE21 Suite WordPress plugin, affecting all versions up to and including 2.3.1. The root cause is the plugin's practice of logging sensitive authentication credentials and JWT tokens to a log file (commonly plugin-log.txt) located within the plugin's directory. This file is web-accessible by default, meaning any unauthenticated user can retrieve it via a direct HTTP request. The log entries may include usernames, JWT tokens, and other authentication data.
If an administrator has used the plugin's custom authentication feature, their credentials or tokens may be present in the log file. Attackers can use these tokens or credentials to authenticate as other users, including administrators, resulting in a complete site takeover. This vulnerability is categorized under CWE-532 (Insertion of Sensitive Information into Log File).
No public code snippets are available for this vulnerability. The exploit does not require authentication and relies solely on the ability to access the log file via HTTP.
Affected Systems and Versions
- Product: CE21 Suite WordPress plugin
- Affected versions: All versions up to and including 2.3.1
- Any site with the plugin installed and log files accessible via HTTP is vulnerable
Vendor Security History
CE21 Suite has been the subject of several critical vulnerabilities:
- CVE-2024-10284: Authentication bypass due to a hardcoded encryption key
- CVE-2024-10285: JWT token disclosure via log file exposure
- CVE-2024-10294: Missing authorization on plugin settings changes
The vendor has not released patches for these vulnerabilities, and the plugin was removed from the WordPress.org repository. This indicates a lack of ongoing security maintenance and a poor patch response record.
