GHSA-7ww3-xvf5-cxwm: Missing Defense-in-Depth HTTP Headers in ciguard Web UI
Vulnerability ID: GHSA-7WW3-XVF5-CXWM
CVSS Score: 4.3
Published: 2026-05-05
The ciguard Web UI (versions prior to 0.8.2) lacks essential HTTP security headers. This absence exposes the application to client-side attacks, including Clickjacking, potential Cross-Site Scripting (XSS) via lack of Content-Security-Policy (CSP), and supply-chain risks due to missing Sub-Resource Integrity (SRI) checks on external CDN assets.
TL;DR
ciguard < 0.8.2 is missing critical security headers like CSP and X-Frame-Options, allowing clickjacking and CDN-based attacks. The vulnerability was patched in version 0.8.2 by implementing custom security middleware.
⚠️ Exploit Status: POC
Technical Details
- CWE ID: CWE-693, CWE-1021, CWE-353
- Attack Vector: Network
- CVSS v3.1 Score: 4.3 (Medium)
- User Interaction: Required (UI:R)
- Exploit Status: Proof of Concept (ZAP Scan)
- KEV Status: Not Listed
Affected Systems
- ciguard Web UI
-
ciguard: >= 0.1.0, < 0.8.2 (Fixed in:
0.8.2)
Mitigation Strategies
- Upgrade the ciguard package to version 0.8.2 or higher.
- Implement an intermediate reverse proxy (e.g., Nginx, HAProxy) to inject standard HTTP security headers if direct patching is unavailable.
Remediation Steps:
- Verify the currently installed version of ciguard in your environment.
- Run the package manager update command to fetch version 0.8.2 or greater (e.g.,
pip install ciguard==0.8.3). - Restart the FastAPI/Uvicorn server process serving the Web UI.
- Execute
curl -sI http://localhost:8080/ | grep X-Frameto confirm the presence of the new headers.
