CVE-2025-11928
MediumCVSS 4.4Exploitation Probability (EPSS)
Low risk8th percentile - higher than 8% of all known CVEs
Summary
The CSS & JavaScript Toolbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 12.0.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Risk Assessment
An attacker with administrator privileges can execute malicious JavaScript in other users' browsers, potentially leading to data theft or session hijacking, especially in multi-site environments.
Recommendation
Update the plugin to a version newer than 12.0.5 or disable it if no update is available. Verify that unfiltered_html is disabled and limit the number of administrators.
