CVE-2024-2127 is a stored cross-site scripting vulnerability (CWE-79) in the Page Builder: Pagelayer WordPress plugin by softaculous, affecting all versions up to and including 1.8.3. The issue results from insufficient input sanitization and output escaping of custom attributes, permitting authenticated users with contributor or higher privileges to inject arbitrary web scripts into pages. These scripts execute in the context of any user who accesses the injected page, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and partial impact on confidentiality and integrity.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages created with the plugin. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user sessions or performing unauthorized actions within the context of the site. The vulnerability does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level permissions to trusted users only and consider disabling or replacing the vulnerable plugin to prevent exploitation.
