Introduction
Attackers can extract authentication credentials from public log files on WordPress sites running vulnerable versions of the CE21 Suite plugin. If an administrator has ever used the plugin's authentication feature, the exposure can lead to full administrative compromise.
About CE21 Suite: CE21, LLC develops plugins that integrate CE21 platform features into WordPress, and CE21 Suite is a niche tool for connecting WordPress with CE21's platform services. It was never widely deployed. When it was removed from the WordPress.org repository it had about 30 active installations, a small but nonzero base, and several critical vulnerabilities in it have received CVEs.
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 that the plugin writes sensitive authentication credentials and JWT tokens to a log file in its own directory, commonly plugin-log.txt. That file is web-accessible by default, so any unauthenticated user can retrieve it with 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 in the log file. Attackers can use those tokens or credentials to authenticate as other users, including administrators, and take over the site completely. The vulnerability is categorized under CWE-532 (Insertion of Sensitive Information into Log File).
No public code snippets are available for this vulnerability. The exploit needs no authentication, only the ability to reach the log file over 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 had several other 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 any of them, and the plugin was removed from the WordPress.org repository. That indicates no ongoing security maintenance and a poor record of responding with patches.
