CVE-2026-93970: aiyiyi121 SxDevOps Auth Bypass Vulnerability

CVE-2026-93970 Overview

CVE-2026-93970 is a hard-coded credentials vulnerability [CWE-259] in aiyiyi121 SxDevOps versions 1.0 and 1.1. The flaw resides in the Settings Handler component, specifically within the backend/sxdevops/settings.py file. An attacker can leverage the embedded credentials remotely without prior authentication or user interaction. The vendor was contacted early, responded professionally, and released a fixed version identified by commit 2b4bf8585c3e731e7a8af30801ea46680bc783f9.

Critical Impact

Remote attackers can use hard-coded credentials embedded in the SxDevOps configuration to gain unauthorized access to the application, potentially compromising confidentiality, integrity, and availability of the platform.

Affected Products

• aiyiyi121 SxDevOps 1.0
• aiyiyi121 SxDevOps 1.1
• Component: Settings Handler (backend/sxdevops/settings.py)

Technical Details for CVE-2026-93970

Vulnerability Analysis

The vulnerability originates in the SxDevOps Django-style settings module. Developers embedded static credential values directly inside backend/sxdevops/settings.py, making them part of the shipped source distribution. Because every deployment of SxDevOps 1.0 and 1.1 inherits the identical credential material, one leaked value compromises every unpatched instance.

The issue is classified under [CWE-259] Use of Hard-coded Password. The VulDB Vulnerability #407929 entry confirms remote exploitability with low attack complexity and no authentication required.

Root Cause

The root cause is the presence of static secret values in a source-controlled configuration file rather than sourcing them from environment variables, a secrets manager, or a runtime-generated key store. Because settings.py ships with the application, the credentials are discoverable through public source inspection on the SxDevOps GitHub Repository.

Attack Vector

Exploitation is performed over the network against any exposed SxDevOps 1.0 or 1.1 deployment. An attacker retrieves the known credential from the public repository and authenticates against the target instance. No prior privileges or user interaction are required.

The patch hardens security controls across the AIOps backend and removes the static credential values from settings.py. Review the full diff in the GitHub Commit 2b4bf85 and the tracking issue at GitHub Issue #16.

Detection Methods for CVE-2026-93970

Indicators of Compromise

• Successful authentication events on SxDevOps instances using the credential values distributed in the pre-patch backend/sxdevops/settings.py file.
• Unexpected administrative configuration changes or new API tokens created on SxDevOps 1.0 or 1.1 deployments.
• Access to sensitive endpoints originating from IP addresses that have never previously interacted with the application.

Detection Strategies

• Perform a source scan of deployed SxDevOps installations to confirm whether settings.py still contains the pre-patch credential material.
• Compare deployed commit hashes against 2b4bf8585c3e731e7a8af30801ea46680bc783f9 to identify unpatched hosts.
• Baseline authentication behavior and alert on logins that succeed using the known static credentials.

Monitoring Recommendations

• Aggregate SxDevOps application and web server logs into a centralized analytics platform for anomaly detection.
• Enable alerts for repeated failed logins followed by a successful login from the same source, which indicates credential probing.
• Continuously monitor outbound connections from SxDevOps hosts for signs of post-compromise data exfiltration.

How to Mitigate CVE-2026-93970

Immediate Actions Required

• Update SxDevOps to the patched build that includes commit 2b4bf8585c3e731e7a8af30801ea46680bc783f9.
• Rotate every credential, API key, and secret that was ever stored in backend/sxdevops/settings.py.
• Restrict network exposure of SxDevOps management interfaces until the patch has been verified.

Patch Information

The vendor released the fix in commit 2b4bf8585c3e731e7a8af30801ea46680bc783f9. Administrators should pull the updated source from the SxDevOps GitHub Repository and redeploy. Details are tracked at VulDB CVE-2026-93970 and GitHub Issue #16.

Workarounds

• Replace hard-coded values in settings.py with environment variables or a secrets manager before restarting the service.
• Place SxDevOps behind an authenticated reverse proxy or VPN to reduce remote attack surface.
• Apply network access control lists limiting inbound traffic to known administrator source ranges.

# Verify the deployed SxDevOps commit matches the patched revision
cd /opt/sxdevops
git fetch origin
git checkout 2b4bf8585c3e731e7a8af30801ea46680bc783f9

# Move secrets out of settings.py into environment variables
export SXDEVOPS_SECRET_KEY="$(python -c 'import secrets;print(secrets.token_urlsafe(64))')"
export SXDEVOPS_DB_PASSWORD="$(python -c 'import secrets;print(secrets.token_urlsafe(32))')"

# Restart the backend service after rotation
systemctl restart sxdevops-backend
