Stored Cross-Site Scripting in Pagelayer WordPress Plugin

CVE-2023-6738

What is CVE-2023-6738?

The Pagelayer WordPress plugin is susceptible to Stored Cross-Site Scripting vulnerabilities due to inadequate input sanitization and output escaping in the 'pagelayer_header_code', 'pagelayer_body_open_code', and 'pagelayer_footer_code' meta fields. Authenticated attackers with contributor-level permissions can exploit this flaw to inject malicious scripts that execute whenever a user accesses the compromised page. This issue seems to have resurfaced following a fix in version 1.7.7.
