CVE-2025-31899: Awesome Logos XSS Vulnerability

CVE-2025-31899 is a reflected cross-site scripting flaw in the Awesome Logos WordPress plugin that enables attackers to inject malicious scripts. This article covers technical details, affected versions, and mitigation.

Published: April 28, 2026

CVE-2025-31899 Overview

CVE-2025-31899 is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the Awesome Logos WordPress plugin developed by wpshopee. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Reflected XSS vulnerabilities occur when user-supplied input is immediately returned by a web application without proper sanitization or encoding. In this case, the Awesome Logos plugin fails to adequately validate and escape user input before reflecting it back in the HTTP response, enabling attackers to craft malicious URLs that execute arbitrary JavaScript when clicked by unsuspecting users.

Critical Impact

Attackers can steal session cookies, hijack user accounts, deface web pages, redirect users to malicious sites, or perform actions on behalf of authenticated WordPress administrators.

Affected Products

  • WordPress Awesome Logos plugin version 1.2 and earlier
  • All WordPress installations using vulnerable versions of the awesome-logos plugin
  • Sites without Web Application Firewall (WAF) protection against XSS attacks

Technical Details for CVE-2025-31899

Vulnerability Analysis

This Reflected XSS vulnerability allows unauthenticated attackers to inject malicious scripts into web pages served by WordPress sites running the vulnerable Awesome Logos plugin. The attack requires user interaction—specifically, a victim must click on a specially crafted malicious link or visit a page containing the malicious payload.

The vulnerability has a changed scope, meaning successful exploitation can impact resources beyond the vulnerable component itself. An attacker exploiting this flaw can potentially compromise the confidentiality, integrity, and availability of data within the victim's browser context, including access to sensitive session information and the ability to perform unauthorized actions.

Root Cause

The root cause of CVE-2025-31899 lies in insufficient input validation and output encoding within the Awesome Logos plugin. The plugin fails to properly sanitize user-controlled input before incorporating it into dynamically generated HTML content. This violates secure coding practices outlined in CWE-79 (Improper Neutralization of Input During Web Page Generation).

WordPress plugins that handle user input must implement proper escaping functions such as esc_html(), esc_attr(), esc_url(), and wp_kses() to prevent script injection. The absence or improper implementation of these security controls enables the reflected XSS attack vector.

Attack Vector

The attack is executed over the network and requires no authentication or special privileges. An attacker crafts a malicious URL containing JavaScript payload embedded in a vulnerable parameter processed by the Awesome Logos plugin. When a victim clicks the link, the malicious script executes in their browser with the same privileges as the victim's session.

Typical attack scenarios include:

  1. Sending phishing emails containing malicious links to WordPress administrators
  2. Posting malicious links on forums, social media, or comment sections
  3. Embedding the malicious URL in legitimate-looking content to encourage clicks

The vulnerability manifests when user-supplied input is reflected in the page output without proper encoding. Due to the nature of Reflected XSS, attackers can leverage this flaw to steal authentication cookies, capture keystrokes, redirect users to malicious sites, or perform administrative actions if the victim has elevated privileges. See the Patchstack WordPress Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-31899

Indicators of Compromise

  • Unusual URL parameters containing JavaScript code, HTML tags, or encoded script payloads in web server access logs
  • User reports of unexpected pop-ups, redirects, or suspicious behavior when visiting plugin-related pages
  • Web Application Firewall logs showing blocked XSS attempts targeting the awesome-logos plugin paths
  • Browser console errors indicating attempted script execution from untrusted sources

Detection Strategies

  • Deploy SentinelOne Singularity XDR to monitor endpoint behavior for suspicious browser activity and script execution patterns
  • Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in URL parameters
  • Enable WordPress security plugins with real-time scanning capabilities to identify vulnerable plugin versions
  • Configure Content Security Policy (CSP) headers to restrict script execution and report policy violations

Monitoring Recommendations

  • Review web server access logs for requests containing suspicious characters such as <script>, javascript:, onerror=, and encoded variants
  • Monitor for anomalous administrative actions that may indicate session hijacking following XSS exploitation
  • Set up automated vulnerability scanning to identify outdated WordPress plugins across your infrastructure
  • Enable browser-based XSS protection headers and monitor for Content Security Policy violation reports

How to Mitigate CVE-2025-31899

Immediate Actions Required

  • Update the Awesome Logos plugin to a patched version immediately if one is available from the vendor
  • If no patch is available, consider deactivating and removing the awesome-logos plugin until a fix is released
  • Implement Web Application Firewall rules to filter XSS payloads targeting the affected plugin
  • Review user accounts for signs of compromise and reset passwords for any potentially affected administrators

Patch Information

Check the WordPress plugin repository and the Patchstack WordPress Vulnerability Report for patch availability and updated versions. Organizations should prioritize updating to a version newer than 1.2 once released by the vendor.

Until an official patch is available, implement defense-in-depth measures including input validation, output encoding, and Content Security Policy headers to reduce exploitation risk.

Workarounds

  • Disable the Awesome Logos plugin if it is not essential for site functionality until a patch is available
  • Implement strict Content Security Policy headers to prevent inline script execution and mitigate XSS impact
  • Deploy a Web Application Firewall with XSS protection rules to filter malicious payloads before they reach the application
  • Restrict administrative access to trusted IP addresses to limit the impact of potential session hijacking
bash
# Add Content Security Policy header in .htaccess to mitigate XSS
# Place in WordPress root directory

<IfModule mod_headers.c>
    Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'self';"
    Header set X-Content-Type-Options "nosniff"
    Header set X-XSS-Protection "1; mode=block"
</IfModule>
