Server-Side Request Forgery in Qwen-Agent

Publication date: 2026-08-28

Last updated on: 2026-08-28

Assigner: VulnCheck

Description

Qwen-Agent through 0.0.34 contains a server-side request forgery vulnerability in the document parsing path that treats caller-supplied paths as URLs without scheme restriction or host validation. Attackers can reach the unauthenticated Gradio interface to make the server issue HTTP requests to arbitrary internal addresses including metadata services and read retrieved content through parsed document output.

Attack-Flow Graph

Executive Summary

CVE-2026-82268 is a Server-Side Request Forgery (SSRF) vulnerability in Qwen-Agent versions up to 0.0.34. It allows unauthenticated attackers to exploit the document parsing path by supplying paths treated as URLs without proper scheme or host validation. This forces the server to make HTTP requests to arbitrary internal addresses, including metadata services, and read the retrieved content through parsed document output.

Detection Guidance

Check if Qwen-Agent versions up to 0.0.34 are installed by running: pip show qwen-agent. Inspect network traffic for outbound HTTP requests to internal or unexpected addresses. Monitor Gradio interface logs for unauthenticated access attempts or unusual document parsing requests.

Impact Analysis

This vulnerability can allow attackers to access internal network services, perform cloud metadata exfiltration (e.g., stealing IAM credentials on AWS), scan internal networks, and retrieve sensitive data from private services. It may also lead to unauthorized data exposure or further network compromise depending on the server's environment.

Compliance Impact

This SSRF vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Organizations using affected Qwen-Agent versions may face compliance breaches, legal penalties, and reputational damage due to potential data leaks or unauthorized access to internal systems.

Mitigation Strategies

Upgrade Qwen-Agent to a patched version if available. Restrict network access to the Gradio interface using firewalls. Disable document parsing from untrusted URLs or implement strict URL validation. Block requests to private IP ranges and loopback addresses in the application configuration.
