The Bold Page Builder plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated attackers with contributor-level privileges or above can inject arbitrary HTML tags containing malicious scripts because the plugin does not adequately sanitize or escape user-supplied attributes. This leads to script execution in the context of users viewing the compromised pages. The vulnerability affects all versions up to 4.8.8 and has a CVSS 3.1 base score of 6.4, indicating a medium severity impact. No patch or official fix details are currently available.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages built with the Bold Page Builder plugin. These scripts execute in the browsers of users who visit the infected pages, potentially leading to unauthorized actions or data exposure limited to the scope of the injected scripts. The vulnerability does not affect availability but impacts confidentiality and integrity to a limited extent.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Bold Page Builder plugin to reduce risk. Monitor vendor channels for updates and apply patches promptly once available.
