Stored Cross-Site Scripting Vulnerability in Fleet Manager Plugin for WordPress

CVE-2025-12538

What is CVE-2025-12538?

The Fleet Manager plugin for WordPress suffers from a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping in its admin settings. This issue affects all versions up to and including 2.5.1. Authenticated users with editor-level permissions or higher can exploit this weakness to inject arbitrary scripts. These scripts will execute whenever a user accesses the compromised page. This vulnerability is particularly concerning for multi-site setups and instances where the unfiltered_html option is disabled, as it broadens the impact and exploitability.
