## What is CVE-2024-8502?

CVE-2024-8502 is a critical unsafe deserialization vulnerability in modelscope/agentscope, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2024-8502 and fix it if it is affected.

What it is: CVE-2024-8502 is a critical unsafe deserialization vulnerability in modelscope/agentscope, published on 20 Mar 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-8502 exists.

Affected packages and fixed versions:
- agentscope (PyPI): affected all versions up to 0.0.6a3; no fix listed
- agentscope (PyPI): affected all versions up to 0.0.6a3; no fix listed
- agentscope (PyPI): affected all versions up to 0.0.6a3; no fix listed

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
