DescriptionCVE.org

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in CodeRevolution Echo RSS Feed Post Generator Plugin for WordPress allows Reflected XSS. This issue affects Echo RSS Feed Post Generator Plugin for WordPress: from n/a through 5.4.8.1.

AnalysisAI

Reflected Cross-Site Scripting (XSS) vulnerability in the CodeRevolution Echo RSS Feed Post Generator Plugin for WordPress affecting versions through 5.4.8.1. An unauthenticated attacker can inject malicious scripts into web pages viewed by users with no special privileges required, potentially leading to session hijacking, credential theft, or malware distribution. The CVSS 7.1 score reflects the moderate severity with network attack vector and user interaction requirement.

Technical ContextAI

This vulnerability stems from improper input neutralization (CWE-79) during dynamic web page generation in the WordPress plugin ecosystem. The Echo RSS Feed Post Generator plugin processes RSS feed data and generates WordPress posts without adequate output encoding or input validation. The reflected nature of this XSS indicates the malicious payload is not stored in the database but rather passed through request parameters (query strings, form data, or HTTP headers) and reflected back to the victim's browser without sanitization. WordPress plugins operating within the wp-admin and frontend contexts must adhere to strict sanitization (sanitize_text_field, wp_kses_post) and escaping (esc_html, esc_attr, wp_kses_data) practices. The vulnerability likely exists in RSS feed URL handling, feed content parsing, or configuration parameter processing where user-controlled input reaches output functions without proper escaping using WordPress's native sanitization APIs.

RemediationAI

Immediate remediation steps: (1) Update the Echo RSS Feed Post Generator plugin to version 5.4.8.2 or later (version number to be confirmed from vendor release notes—patch version must exceed 5.4.8.1). (2) If patch is unavailable, disable the plugin: wp-cli plugin deactivate echo-rss-feed-post-generator, then delete or quarantine. (3) For affected sites, conduct security audit of generated posts for injected scripts. Workarounds pending patch: (1) Implement WordPress security headers (Content-Security-Policy) to restrict inline script execution, reducing XSS impact scope. (2) Apply Web Application Firewall (WAF) rules to filter XSS payloads in RSS feed URLs and POST parameters. (3) Restrict RSS feed source URLs to trusted, validated domains only via plugin settings. (4) Monitor user activity logs for suspicious parameter values in feed processing requests. Refer to official CodeRevolution security advisory and WordPress.org plugin repository for patch availability and vendor guidance.
