CVE-2026-22918
📋 TL;DR
This CVE describes a clickjacking vulnerability where attackers can trick users into performing unintended actions on web interfaces, potentially leading to sensitive data extraction. It affects web applications or interfaces that lack proper frame-busting or X-Frame-Options protections. Users interacting with vulnerable web interfaces are at risk.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers could extract sensitive user data, manipulate user accounts, or perform unauthorized transactions by tricking users into clicking hidden interface elements.
Likely Case
Attackers create malicious web pages that overlay legitimate interfaces, tricking users into clicking buttons or links that perform unintended actions like changing settings or revealing information.
If Mitigated
With proper clickjacking protections implemented, users are protected from malicious framing and the attack surface is eliminated.
🎯 Exploit Status
Clickjacking attacks are well-known and relatively easy to implement. Exploitation requires user interaction with malicious web pages.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://sick.com/psirt
Restart Required: No
Instructions:
1. Check vendor advisory at sick.com/psirt 2. Apply recommended patches or updates 3. Verify implementation of clickjacking protections
🔧 Temporary Workarounds
Implement X-Frame-Options Header
allPrevents web pages from being framed by other sites
Add 'X-Frame-Options: DENY' or 'X-Frame-Options: SAMEORIGIN' to HTTP headers
Implement Content-Security-Policy frame-ancestors
allModern alternative to X-Frame-Options with more granular control
Add 'Content-Security-Policy: frame-ancestors 'none'' to HTTP headers
🧯 If You Can't Patch
- Implement web application firewall rules to add X-Frame-Options headers
- Educate users about clickjacking risks and safe browsing practices
🔍 How to Verify
Check if Vulnerable:
Test web interfaces by attempting to frame them in iframes and checking for X-Frame-Options or CSP headersCheck Version:
Check product documentation or web interface for version informationVerify Fix Applied:
Verify X-Frame-Options: DENY or Content-Security-Policy: frame-ancestors 'none' headers are present in HTTP responses📡 Detection & Monitoring
Log Indicators:
- Unusual user actions from same IP/session
- Multiple failed actions from legitimate users
Network Indicators:
- Requests to web interfaces from unexpected referrers
- Iframe embedding attempts
SIEM Query:
