DescriptionCVE.org

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in QuantumCloud ChatBot for eCommerce – WoowBot woowbot-woocommerce-chatbot allows Stored XSS.This issue affects ChatBot for eCommerce – WoowBot: from n/a through <= 4.6.1.

AnalysisAI

Stored Cross-Site Scripting in QuantumCloud's WoowBot (ChatBot for eCommerce) WordPress plugin allows authenticated low-privileged users to inject persistent malicious scripts that execute in victims' browsers when stored content is rendered. Versions through 4.6.1 are affected, with a scope change confirmed by the CVSS vector (S:C), meaning attacker-controlled JavaScript runs in the context of other users - including administrators. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV.

Technical ContextAI

WoowBot is a WooCommerce-integrated chatbot plugin for WordPress (CPE: cpe:2.3:a:quantumcloud:chatbot_for_ecommerce_-_woowbot:*:*:*:*:*:*:*:*). The root cause is CWE-79 - Improper Neutralization of Input During Web Page Generation - specifically in its Stored XSS variant, where user-supplied input is persisted to the database without adequate sanitization or output encoding, and later rendered into HTML page responses. This is a classic server-side storage flaw: the malicious payload survives across sessions and executes for every subsequent user who views the affected page, unlike Reflected XSS which requires per-request delivery. WordPress plugins are a frequent vector for this class of vulnerability due to inconsistent use of WordPress core escaping functions such as esc_html() and wp_kses_post().

RemediationAI

The primary remediation is to update the WoowBot plugin beyond version 4.6.1; however, an exact patched release version is not confirmed in the available intelligence - consult the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/woowbot-woocommerce-chatbot/vulnerability/wordpress-chatbot-for-ecommerce-woowbot-plugin-4-6-1-cross-site-scripting-xss-vulnerability and the WordPress plugin repository for the latest release. If an immediate update is not possible, a compensating control is to restrict chatbot submission access to only authenticated users with trusted roles (e.g., remove open customer registration or gate chatbot use behind role checks), reducing the PR:L attack surface to already-vetted accounts. A Web Application Firewall rule filtering script injection patterns in chatbot input fields can reduce exploitation likelihood but is not a substitute for patching, as WAF bypass techniques for XSS payloads are well-documented. Site administrators should also review stored chatbot conversation logs for anomalous script tags as an indicator of prior exploitation attempts.
