CVE-2025-67989

5.4 MEDIUM

📋 TL;DR

This Server-Side Request Forgery (SSRF) vulnerability in the LMPixels Kerge WordPress theme allows attackers to make unauthorized requests from the vulnerable server to internal or external systems. It affects all WordPress sites using Kerge theme versions up to and including 4.1.3. Attackers can potentially access internal services, perform port scanning, or interact with cloud metadata services.

💻 Affected Systems

Products:
  • LMPixels Kerge WordPress Theme
Versions: All versions up to and including 4.1.3
Operating Systems: Any OS running WordPress
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects WordPress installations with the Kerge theme active. The vulnerability exists in the theme's code, not WordPress core.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could access internal services, cloud metadata APIs (exposing credentials), perform internal port scanning, or use the server as a proxy for attacks against other systems.

🟠

Likely Case

Information disclosure from internal services, limited internal network reconnaissance, or abuse of the server as a proxy for external attacks.

🟢

If Mitigated

Limited impact if network segmentation restricts internal access and external requests are filtered, though some information disclosure may still occur.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

SSRF vulnerabilities are commonly exploited and weaponized. The public disclosure includes technical details that facilitate exploitation.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version 4.1.4 or later

Vendor Advisory: https://patchstack.com/database/Wordpress/Theme/kerge/vulnerability/wordpress-kerge-theme-4-1-3-server-side-request-forgery-ssrf-vulnerability?_s_id=cve

Restart Required: No

Instructions:

1. Log into WordPress admin panel. 2. Navigate to Appearance > Themes. 3. Find Kerge theme and click 'Update Now' if available. 4. If manual update needed, download latest version from WordPress.org or vendor, upload via FTP/SFTP replacing old files. 5. Clear any caching plugins.

🔧 Temporary Workarounds

Input Validation and Sanitization

all

Add server-side validation to reject or sanitize URLs in user-controlled parameters that trigger external requests.

Network Segmentation

linux

Restrict outbound network access from web servers to only necessary external services using firewall rules.

iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT
iptables -A OUTPUT -p tcp --dport 443 -j ACCEPT
iptables -A OUTPUT -j DROP

🧯 If You Can't Patch

  • Switch to a different WordPress theme temporarily
  • Implement web application firewall (WAF) rules to block SSRF patterns

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel under Appearance > Themes for Kerge theme version. If version is 4.1.3 or lower, system is vulnerable.

Check Version:

wp theme list --field=name,version --format=csv | grep kerge

Verify Fix Applied:

Confirm Kerge theme version is 4.1.4 or higher in WordPress admin. Test SSRF functionality if safe testing environment exists.

📡 Detection & Monitoring

Log Indicators:

  • Unusual outbound HTTP requests from web server to internal IPs or unusual domains
  • Multiple failed connection attempts to internal services from web server

Network Indicators:

  • Web server making unexpected HTTP requests to internal network segments
  • Requests to cloud metadata endpoints (169.254.169.254, etc.)

SIEM Query:

source="web_server_logs" AND (url CONTAINS "internal_ip" OR url CONTAINS "metadata")
