How to Fix CVE-2024-8556

To remediate this vulnerability, upgrade all affected Agentscope dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

agentscope fixed: Latest secure release 
pip install agentscope>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show agentscope

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-8556, inspect your installed packages using pip:

pip show agentscope

Analyze the terminal output to locate any version of Agentscope in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show agentscope command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Agentscope, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A stored cross-site scripting (XSS) vulnerability exists in modelscope/agentscope, as of the latest commit 21161fe on the main branch. The vulnerability occurs in the view for inspecting detailed run information, where a user-controllable string (run ID) is appended and rendered as HTML. This allows an attacker to execute arbitrary JavaScript code in the context of the user's browser.
