Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Maarten Links shortcode links-shortcode allows Stored XSS.This issue affects Links shortcode: from n/a through <= 1.8.3.
AnalysisAI
Stored cross-site scripting in the WordPress Links shortcode plugin up to version 1.8.3 allows authenticated attackers with low privileges to inject malicious scripts via the plugin's shortcode functionality. When a victim views a page containing the crafted shortcode, the injected script executes in their browser, leading to potential session theft, content manipulation, or redirection. No active exploitation or public exploit is reported, and EPSS indicates a low exploitation probability.
Technical ContextAI
The vulnerability arises from improper neutralization of user input when generating web page output (CWE-79) within the Links shortcode plugin for WordPress. Shortcodes in WordPress allow users to embed dynamic content; this plugin fails to sanitize or escape input before rendering it, enabling stored XSS. The affected CPE is the WordPress plugin 'links-shortcode' by Maarten Links, version range up to 1.8.3. The root cause is a lack of output encoding, a classic web application security flaw.
Affected ProductsAI
WordPress plugin 'Links shortcode' versions n/a through 1.8.3 are affected. The vendor advisory is available at Patchstack: https://patchstack.com/database/Wordpress/Plugin/links-shortcode/vulnerability/wordpress-links-shortcode-plugin-1-8-3-cross-site-scripting-xss-vulnerability?_s_id=cve.
RemediationAI
No vendor-released patch version is independently confirmed in the available data. If a fixed version exists (likely above 1.8.3), upgrade immediately. If no update is available, temporarily deactivate the Links shortcode plugin until a patched release is provided. As a workaround, restrict shortcode usage to trusted roles only, but note this may not prevent exploitation if low-privilege users can create posts containing the shortcode. Disabling the plugin entirely eliminates the risk but removes the shortcode functionality.
