CRITICAL 9.8REMOTEDOWNGRADE

CVE-2024-8487 is a critical-severity flaw (CVSS 9.8) affecting agentscope. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A Cross-Origin Resource Sharing (CORS) vulnerability exists in modelscope/agentscope version v0.0.4. The CORS configuration on the agentscope server does not properly restrict access to only trusted origins, allowing any external domain to make requests to the API. This can lead to unauthorized data access, information disclosure, and potential further exploitation, thereby compromising the integrity and confidentiality of the system.
