Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Jason C. Memberlite Shortcodes memberlite-shortcodes allows Stored XSS.This issue affects Memberlite Shortcodes: from n/a through <= 1.4.1.
AnalysisAI
Stored cross-site scripting (XSS) in the Memberlite Shortcodes WordPress plugin through version 1.4.1 allows authenticated attackers to inject arbitrary web scripts. This vulnerability can lead to session hijacking or arbitrary actions executed in the context of the victim's browser when they view a page containing malicious shortcode content. No active exploitation or public exploit code has been identified at time of analysis.
Technical ContextAI
The vulnerability stems from improper neutralization of user-supplied shortcode input during web page generation, falling under CWE-79 (Cross-site Scripting). Memberlite Shortcodes is a WordPress plugin that processes custom shortcodes, and insufficient output sanitization allows stored XSS when a shortcode containing a payload is rendered on a page.
Affected ProductsAI
Memberlite Shortcodes WordPress plugin, all versions from n/a through 1.4.1. Reference: https://patchstack.com/database/WordPress/Plugin/memberlite-shortcodes/vulnerability/wordpress-memberlite-shortcodes-plugin-1-4-1-cross-site-scripting-xss-vulnerability?_s_id=cve.
RemediationAI
Update the Memberlite Shortcodes plugin to a version higher than 1.4.1 as soon as a fix is released. If no patched version is available, disable the plugin until an update is provided. As a compensating control, restrict the ability to insert shortcodes (e.g., limited to Editors and Administrators), but note this does not retroactively sanitize existing malicious content. The primary fix path is to upgrade according to vendor guidance in the advisory.
