- CVE-2021-39349, 15 Oct 2021
- The Author Bio Box WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient input validation and sanitization via several parameters found in the ~/includes/admin/class-author-bio-box-admin.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 3.3.1. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled. CVE record
What to do if you run Author Bio Box
If you run Author Bio Box, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
