CVE-2025-31899: Awesome Logos Plugin XSS Vulnerability

CVE-2025-31899 is a reflected cross-site scripting flaw in the Awesome Logos WordPress plugin that allows attackers to inject malicious scripts. This article covers technical details, affected versions up to 1.2, and mitigation.

Updated: May 15, 2026

CVE-2025-31899 Overview

CVE-2025-31899 is a reflected Cross-Site Scripting (XSS) vulnerability affecting the wpshopee Awesome Logos plugin for WordPress. The flaw stems from Improper Neutralization of Input During Web Page Generation [CWE-79]. Attackers can craft malicious URLs that execute arbitrary JavaScript in the victim's browser when clicked. The vulnerability impacts all plugin versions up to and including 1.2. Successful exploitation requires user interaction and can lead to session hijacking, credential theft, and unauthorized actions performed on behalf of the victim.

Critical Impact

Attackers can execute arbitrary JavaScript in a victim's browser session, leading to account takeover, data theft, and administrative privilege abuse when targeting WordPress administrators.

Affected Products

  • wpshopee Awesome Logos WordPress plugin versions up to and including 1.2
  • WordPress sites with the awesome-logos plugin installed and activated
  • All downstream WordPress deployments using the vulnerable plugin

Discovery Timeline

  • 2025-04-03 - CVE-2025-31899 published to the National Vulnerability Database
  • 2026-04-23 - Last updated in NVD database

Technical Details for CVE-2025-31899

Vulnerability Analysis

The Awesome Logos plugin fails to properly sanitize user-supplied input before reflecting it back in HTTP responses. When the plugin renders pages containing attacker-controlled parameters, the unsanitized data is embedded directly into the HTML output. A browser then parses the injected payload as executable JavaScript within the context of the WordPress site's origin.

Reflected XSS requires the victim to visit a specially crafted URL. The attack changes the affected scope, meaning the injected script can access resources beyond the initially vulnerable component. Confidentiality, integrity, and availability are each impacted at a limited level within the victim's browser session.

Root Cause

The root cause is the absence of proper output encoding and input validation in request handlers exposed by the awesome-logos plugin. Input received through HTTP parameters is concatenated into HTML responses without escaping characters such as <, >, ", and '. This allows an attacker to break out of the intended HTML context and inject <script> tags or event handler attributes.

Attack Vector

An attacker delivers a malicious link to a victim through phishing emails, social media, or a compromised website. When the victim clicks the link while authenticated to the WordPress site, the injected JavaScript executes with the victim's privileges. If the target is a logged-in administrator, the attacker can exfiltrate session cookies, modify site content, create rogue administrative accounts, or pivot to further compromise.

The vulnerability manifests during HTTP request processing where parameters are reflected into the rendered page. See the Patchstack Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-31899

Indicators of Compromise

  • HTTP requests to WordPress endpoints containing URL-encoded <script> tags, javascript: URIs, or event handler attributes such as onerror= and onload=
  • Unexpected outbound requests from administrator browsers to attacker-controlled domains shortly after clicking external links
  • Creation of new WordPress administrator accounts or unauthorized plugin installations without corresponding admin activity logs
  • Modified WordPress options or theme files following suspicious admin sessions

Detection Strategies

  • Inspect web server access logs for requests to awesome-logos plugin endpoints containing suspicious characters like <, >, %3C, or %3E
  • Deploy a Web Application Firewall (WAF) with rules targeting reflected XSS payload patterns in query strings and POST bodies
  • Monitor browser-based telemetry for execution of inline scripts originating from WordPress pages serving the plugin
  • Correlate administrator session activity with referrer headers pointing to external or untrusted domains

Monitoring Recommendations

  • Enable verbose logging on WordPress and forward events to a centralized SIEM for analysis
  • Track plugin inventory across WordPress installations to identify hosts running awesome-logos version 1.2 or earlier
  • Alert on anomalous administrator behavior, including off-hours logins and unexpected configuration changes
  • Implement Content Security Policy (CSP) reporting to capture blocked inline script execution attempts

How to Mitigate CVE-2025-31899

Immediate Actions Required

  • Deactivate and remove the Awesome Logos plugin until a patched version is confirmed available from the vendor
  • Audit WordPress administrator accounts and rotate credentials for any users who may have clicked suspicious links
  • Invalidate active WordPress sessions and force re-authentication for all privileged users
  • Review recent plugin, theme, and content changes for unauthorized modifications

Patch Information

No vendor-supplied patch is referenced in the available advisory data. The vulnerability affects all versions through 1.2. Administrators should monitor the Patchstack Vulnerability Report and the official WordPress plugin repository for updates.

Workarounds

  • Remove the awesome-logos plugin entirely and replace it with an actively maintained alternative
  • Deploy a WAF with rules that block reflected XSS payloads targeting WordPress plugin endpoints
  • Implement a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
  • Train administrators to avoid clicking unsolicited links and to access the WordPress admin dashboard from dedicated browser profiles
bash
# Configuration example: Remove vulnerable plugin via WP-CLI
wp plugin deactivate awesome-logos
wp plugin delete awesome-logos

# Verify removal
wp plugin list --status=active | grep -i awesome-logos
