🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Version after 1.0.0

Vendor Advisory: https://wordpress.org/plugins/bee-quick-gallery/#developers

Restart Required: No

Instructions:

1. Log into WordPress admin panel. 2. Go to Plugins → Installed Plugins. 3. Find 'Image Gallery' or 'bee-quick-gallery'. 4. Click 'Update Now' if available. 5. If no update is available, deactivate and delete the plugin immediately.

🔧 Temporary Workarounds

Web Application Firewall (WAF)

all

Deploy a WAF with XSS protection rules to block malicious payloads before they reach the application.

Content Security Policy (CSP)

all

Implement a strict CSP header to prevent execution of inline scripts and restrict script sources.

Header set Content-Security-Policy "default-src 'self'; script-src 'self'"
Add to .htaccess or web server configuration

🧯 If You Can't Patch

  • Deactivate and remove the Image Gallery plugin immediately.
  • Implement network-level filtering to block requests containing suspicious script patterns.

🔍 How to Verify

Check if Vulnerable:

Check WordPress admin panel → Plugins → Installed Plugins. If 'Image Gallery' or 'bee-quick-gallery' shows version 1.0.0 or earlier, you are vulnerable.

Check Version:

wp plugin list --name='bee-quick-gallery' --field=version

Verify Fix Applied:

After updating, verify the plugin version shows higher than 1.0.0. Test by attempting to inject basic XSS payloads into plugin parameters.
