XSS does not directly cause availability impact; all other metrics match authenticated network-accessible DOM-XSS with scope change and required victim interaction.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Plugin Envision Envision Page Builder envision-page-builder allows DOM-Based XSS.This issue affects Envision Page Builder: from n/a through <= 0.22.
AnalysisAI
DOM-Based Cross-Site Scripting in the Envision Page Builder WordPress plugin (versions through 0.22) allows low-privileged authenticated attackers to inject and execute malicious JavaScript in victim browsers via unsanitized page builder input. The scope change (S:C) in the CVSS vector confirms the payload escapes the plugin's own context and can affect the broader WordPress environment, including the admin panel. No public exploit code or active exploitation has been identified at time of analysis, but the stored-or-reflected DOM injection path makes this a realistic avenue for session hijacking or privilege escalation within WordPress installations.
Technical ContextAI
CWE-79 (Improper Neutralization of Input During Web Page Generation) describes failure to encode or sanitize user-supplied content before rendering it in HTML. The DOM-Based XSS variant specifically means the vulnerability exists in client-side JavaScript: user-controlled data flows from a DOM source (e.g., location.hash, URL parameter, or plugin-managed field) into a dangerous sink (e.g., innerHTML, document.write, eval) without sanitization, executing in the victim's browser context. The affected product is identified by CPE cpe:2.3:a:plugin_envision:envision_page_builder:*:*:*:*:*:*:*:*, confirming all releases through version 0.22 of the Envision Page Builder plugin by Plugin Envision are affected. Page builder plugins are high-risk targets for XSS because they process rich, structured user content and often pass it through complex JavaScript rendering pipelines that may bypass standard WordPress sanitization hooks like wp_kses.
RemediationAI
Update the Envision Page Builder plugin to a version beyond 0.22 as soon as a patched release is made available by Plugin Envision via the WordPress plugin repository. The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/envision-page-builder/vulnerability/wordpress-envision-page-builder-plugin-0-22-cross-site-scripting-xss-vulnerability should be monitored for patch confirmation. No exact patched version number was independently confirmed in the available data - do not upgrade blindly to an unverified release. As a compensating control, restrict WordPress user registration and limit the contributor/editor role to trusted users only, since PR:L exploitation requires an authenticated account. Additionally, deploying a Web Application Firewall (WAF) with DOM-XSS rulesets (e.g., Cloudflare, Wordfence, or Sucuri) can reduce exploitation probability at the cost of potential false-positive blocking on legitimate page builder interactions. Disabling the Envision Page Builder plugin entirely until a patch is confirmed removes the attack surface with the trade-off of losing page builder functionality.
