Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Truong Thanh ATP Call Now allows Stored XSS. This issue affects ATP Call Now: from n/a through 1.0.3.
AnalysisAI
Stored cross-site scripting in ATP Call Now WordPress plugin up to version 1.0.3 allows authenticated users with high privileges to inject malicious scripts that execute when other users view affected pages. No public exploit or active exploitation identified; EPSS score is low (0.04%).
Technical ContextAI
The vulnerability is a stored cross-site scripting (XSS) issue in the ATP Call Now WordPress plugin, which provides click-to-call functionality. The root cause is improper neutralization of user-supplied input during web page generation (CWE-79). The plugin fails to sanitize or escape input before storing it, allowing attackers with high privileges (e.g., administrators) to inject arbitrary JavaScript that executes in the context of other users' browsers. The CVSS vector indicates a network attack vector, low attack complexity, high privileges required, and user interaction needed.
RemediationAI
Update ATP Call Now plugin to version 1.0.4 or later, which contains the fix. The vendor advisory from Patchstack provides details. As a workaround, restrict plugin usage to trusted administrators only and implement a web application firewall (WAF) to filter XSS payloads. Note that disabling the plugin entirely may affect click-to-call functionality.
