CVE-2025-68669

9.6 CRITICAL

📋 TL;DR

This CVE describes a remote code execution vulnerability in the 5ire AI assistant desktop application. The vulnerability allows attackers to execute arbitrary code by exploiting insecure HTML rendering in Mermaid diagram nodes due to a 'loose' security configuration. Users running 5ire version 0.15.2 or earlier are affected.

💻 Affected Systems

Products:
  • 5ire AI Assistant
Versions: 0.15.2 and prior versions
Operating Systems: Windows, macOS, Linux
Default Config Vulnerable: ⚠️ Yes
Notes: All installations with default configuration are vulnerable. The vulnerability is in the markdown rendering component.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to execute arbitrary commands, steal sensitive data, install malware, or pivot to other systems.

🟠

Likely Case

Local privilege escalation or arbitrary code execution within the application context, potentially leading to data theft or further system exploitation.

🟢

If Mitigated

Limited impact if application runs with minimal privileges and in isolated environments, though code execution would still be possible.

🌐 Internet-Facing: MEDIUM - While primarily a desktop application, if exposed through web interfaces or remote access, risk increases significantly.
🏢 Internal Only: HIGH - The vulnerability exists in the core application and can be exploited through normal usage with malicious content.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires user interaction (viewing malicious content) but no authentication. The vulnerability is straightforward to exploit once malicious content is crafted.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not available

Vendor Advisory: https://github.com/nanbingxyz/5ire/security/advisories/GHSA-5hpf-p8fw-j349

Restart Required: Yes

Instructions:

1. Monitor the GitHub repository for security updates. 2. When a patched version is released, download and install it. 3. Restart the application after installation.

🔧 Temporary Workarounds

Disable Mermaid Diagram Support

all

Modify the application configuration to disable Mermaid diagram rendering or set securityLevel to 'strict'

Edit useMarkdown.ts line 156: change securityLevel from 'loose' to 'strict'

Application Sandboxing

all

Run 5ire in a sandboxed or containerized environment to limit potential damage from exploitation

🧯 If You Can't Patch

  • Immediately stop using 5ire version 0.15.2 or earlier and switch to alternative software
  • Implement strict network segmentation and monitor for suspicious activity from systems running vulnerable versions

🔍 How to Verify

Check if Vulnerable:

Check the application version in settings or about dialog. If version is 0.15.2 or lower, you are vulnerable.

Check Version:

Check application settings or run: 5ire --version (if available)

Verify Fix Applied:

After applying any workaround, test with safe Mermaid diagrams containing HTML tags to ensure they are not rendered.

📡 Detection & Monitoring

Log Indicators:

  • Unusual process spawns from 5ire application
  • Unexpected network connections from 5ire process
  • Error logs related to markdown parsing or Mermaid rendering

Network Indicators:

  • Outbound connections to unexpected destinations from 5ire process
  • DNS requests for command and control domains

SIEM Query:

process_name:"5ire" AND (process_spawn:true OR network_connection:true)
