Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the RpcAgentServerLauncher class of modelscope/agentscope v0.0.6a3 allows for remote code execution (RCE) via deserialization of untrusted data using the dill library. The issue occurs in the AgentServerServicer.create_agent method, where serialized input is deserialized using dill.loads, enabling an attacker to execute arbitrary commands on the server.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A deserialization vulnerability in modelscope/agentscope v0.0.6a3 allows remote code execution through the AgentServerServicer.create_agent method, which uses dill.loads on untrusted serialized input. An attacker can craft malicious serialized data that executes arbitrary commands when deserialized by the server.

MitigationReplace dill.loads with safe deserialization methods, implement input validation on serialized data, or migrate to safer serialization formats that do not allow arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if AgentScope is installed
    Run 'pip show agentscope' or check your Python environment for the agentscope package
    Affected if agentscope version is v0.0.6a3 or earlier (any version that includes the vulnerable AgentServerServicer.create_agent method)
  2. Verify the installed version
    Check the package version output from 'pip show agentscope' or import the package and print its __version__ attribute
    Affected if The version listed is v0.0.6a3 or any version prior to a fix being applied to this vulnerability
  3. Locate AgentServerServicer usage in your codebase
    Search your project files for imports of 'AgentServerServicer' or 'agentscope' and usages of the 'create_agent' method
    Affected if Your code imports and uses AgentServerServicer with the create_agent method to handle incoming serialized data
  4. Inspect if dill deserialization is used
    Search for 'dill.loads' in your codebase, particularly within AgentServerServicer or agent creation logic
    Affected if Your environment uses dill.loads to deserialize untrusted input without validation before the create_agent method processes it

You are affected if you have modelscope/agentscope installed at version v0.0.6a3 or earlier AND your application uses AgentServerServicer.create_agent with dill.loads to deserialize untrusted data.
