CVE-2025-58357 Overview
CVE-2025-58357 is a critical Cross-Site Scripting (XSS) vulnerability affecting 5ire, a cross-platform desktop artificial intelligence assistant and model context protocol (MCP) client. Version 0.13.2 contains a vulnerability in the chat page's script gadgets that enables content injection attacks through multiple vectors including malicious prompt injection pages, compromised MCP servers, and exploited tool integrations.
Critical Impact
This vulnerability allows attackers to inject malicious content through the AI assistant's chat interface, potentially leading to arbitrary code execution within the desktop application context, data exfiltration, and compromise of user sessions.
Affected Products
- 5ire version 0.13.2
- 5ire Desktop AI Assistant (cross-platform)
- Systems using 5ire MCP client integrations

Technical Details for CVE-2025-58357
Vulnerability Analysis
This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting (XSS). The flaw exists in the chat page's script gadgets within the 5ire desktop application, which fails to properly sanitize and validate content before rendering it in the user interface.
The attack surface is particularly concerning due to the nature of AI assistant applications, which inherently process and display untrusted content from multiple sources. In this case, three distinct attack vectors have been identified: malicious prompt injection pages that can embed payloads in AI responses, compromised MCP (Model Context Protocol) servers that can inject malicious content during protocol communications, and exploited tool integrations that can deliver payloads through the application's extensibility features.
The network-based attack vector with low complexity indicates that exploitation can be achieved remotely with minimal technical sophistication. The requirement for user interaction suggests that social engineering or crafted content delivery plays a role in successful exploitation. The scope change characteristic indicates that successful exploitation can impact resources beyond the vulnerable component's security scope.
Root Cause
The root cause of CVE-2025-58357 lies in insufficient input validation and output encoding within the 5ire chat page's script gadget handling mechanism. The application fails to properly sanitize content received from external sources before rendering it in the Electron-based desktop interface, allowing malicious scripts to execute within the application context.
Desktop AI assistants present unique security challenges as they must process diverse content types from AI models, external tools, and user inputs while maintaining security boundaries. The vulnerable version does not adequately enforce these boundaries when handling script gadgets in the chat interface.
Attack Vector
The vulnerability can be exploited through three primary vectors:
Malicious Prompt Injection Pages: An attacker can craft web pages or documents containing prompt injection payloads that, when processed by the AI assistant, result in malicious content being rendered in the chat interface with embedded scripts.
Compromised MCP Servers: The Model Context Protocol facilitates communication between the AI assistant and external servers. A compromised or malicious MCP server can inject payloads during protocol exchanges that are subsequently rendered without proper sanitization.
Exploited Tool Integrations: 5ire supports various tool integrations to extend functionality. Malicious or compromised tools can leverage this integration pathway to inject content that executes within the application's security context.
The vulnerability exploitation does not require authentication, making it accessible to remote attackers who can deliver crafted content through any of these channels.
Detection Methods for CVE-2025-58357
Indicators of Compromise
- Unexpected script execution or JavaScript errors within the 5ire application logs
- Unusual network connections initiated from the 5ire process to unknown external domains
- Modifications to application configuration files or user data stores
- Suspicious MCP server connections or tool integration activities in application telemetry
Detection Strategies
- Monitor for anomalous behavior in 5ire application processes, including unexpected child process spawning or network activity
- Implement application-level logging to capture chat page content rendering events and script gadget executions
- Review MCP server configurations and audit tool integrations for unauthorized modifications
- Deploy endpoint detection solutions to identify XSS-related patterns in desktop application contexts
Monitoring Recommendations
- Enable verbose logging in 5ire to capture detailed information about content rendering and script execution
- Configure network monitoring to alert on unexpected outbound connections from the 5ire application
- Implement file integrity monitoring for 5ire configuration and data directories
- Regularly audit connected MCP servers and installed tool integrations
How to Mitigate CVE-2025-58357
Immediate Actions Required
- Upgrade 5ire to version 0.14.0 or later immediately to address this vulnerability
- Review and audit all configured MCP server connections, removing any untrusted or unnecessary connections
- Disable or remove tool integrations that are not actively required until the upgrade is complete
- Avoid processing untrusted content or visiting potentially malicious prompt injection pages until patched
Patch Information
The vulnerability is fixed in 5ire version 0.14.0. Users should upgrade immediately by downloading the latest release from the official GitHub releases page. The security advisory with full details is available via the GitHub Security Advisory GHSA-8527-3cch-95gf.
Workarounds
- Restrict usage of 5ire to trusted content sources only until the upgrade can be applied
- Disconnect from all MCP servers temporarily if immediate patching is not possible
- Disable all third-party tool integrations until upgrading to the patched version
- Consider using network segmentation to limit the impact of potential exploitation
# Upgrade 5ire to patched version
# Download latest release from GitHub
# https://github.com/nanbingxyz/5ire/releases/tag/v0.14.0
# Verify installed version after upgrade
# Ensure version shows 0.14.0 or higher in application settings
