CVE-2026-5585: Tencent AI-Infra-Guard Disclosure Flaw

CVE-2026-5585 Overview

A vulnerability has been identified in Tencent AI-Infra-Guard 4.0 that allows remote information disclosure through the Task Detail Endpoint. The affected component is located in common/websocket/task_manager.go, where improper handling of task details can expose sensitive information to unauthorized actors. The exploit has been made public and could be used by attackers. The vendor was contacted early about this disclosure but did not respond in any way.

Critical Impact

Remote attackers can exploit this vulnerability to access sensitive task information without authentication, potentially exposing internal system details, configuration data, or other confidential information managed by the AI-Infra-Guard platform.

Technical Details for CVE-2026-5585

Vulnerability Analysis

This vulnerability is classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw exists within the Task Detail Endpoint functionality implemented in the task_manager.go file under the common/websocket/ directory. The information disclosure occurs when the endpoint fails to properly validate access permissions before returning task details to requesting clients.

The vulnerability can be exploited remotely over the network without requiring any user interaction or authentication. While the confidentiality impact is limited, the ease of exploitation makes this a concerning issue for organizations using AI-Infra-Guard 4.0 in production environments.

Root Cause

The root cause of this vulnerability lies in insufficient access control mechanisms within the Task Detail Endpoint. The task_manager.go component does not properly verify whether the requesting user has authorization to view the requested task details before returning the information. This allows unauthenticated or unauthorized users to query and retrieve task information that should be restricted.

Attack Vector

The attack vector is network-based, requiring no local access to the target system. An attacker can remotely interact with the Task Detail Endpoint via WebSocket connections to extract sensitive information. The vulnerability requires low attack complexity with no special conditions or prerequisites needed for exploitation.

The exploitation mechanism involves sending crafted requests to the WebSocket-based Task Detail Endpoint. Due to missing authorization checks in the task_manager.go handler, the server returns task details without validating whether the requester should have access to that information. For technical details and proof-of-concept information, refer to the GitHub PoC Repository.

Detection Methods for CVE-2026-5585

Indicators of Compromise

• Unusual volume of WebSocket requests to the Task Detail Endpoint from external IP addresses
• Multiple rapid-fire task detail queries from a single source attempting to enumerate task IDs
• Access log entries showing requests to /task/ or similar endpoints without corresponding authentication events

Detection Strategies

• Implement monitoring for WebSocket connections to the Task Detail Endpoint that originate from unauthorized sources
• Review application logs for patterns of information disclosure attempts, including sequential task ID enumeration
• Deploy network intrusion detection signatures to identify exploitation attempts against the task_manager.go endpoint

Monitoring Recommendations

• Enable detailed logging for all WebSocket endpoint interactions in AI-Infra-Guard
• Monitor for anomalous patterns in task detail requests, particularly from unauthenticated sessions
• Configure alerts for high-frequency queries to task management endpoints from single IP addresses

How to Mitigate CVE-2026-5585

Immediate Actions Required

• Restrict network access to the AI-Infra-Guard Task Detail Endpoint using firewall rules or network segmentation
• Implement authentication requirements for all WebSocket endpoints if not already enforced
• Review and audit current task data exposure to assess potential information leakage

Patch Information

At the time of publication, no official patch has been released by Tencent. The vendor was contacted about this disclosure but did not respond. Organizations should monitor for security updates and apply patches as soon as they become available. For additional technical details and threat intelligence, refer to the VulDB entry.

Workarounds

• Place AI-Infra-Guard behind a reverse proxy that enforces authentication before allowing access to WebSocket endpoints
• Implement IP whitelisting to restrict access to the Task Detail Endpoint to trusted internal networks only
• Deploy a Web Application Firewall (WAF) to filter and monitor requests to vulnerable endpoints

# Example: Restrict access to AI-Infra-Guard endpoints using iptables
# Allow only trusted internal networks to access the service port
iptables -A INPUT -p tcp --dport 8080 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
