Low risk2th percentile - higher than 2% of all known CVEs
Summary
In MetaGPT up to version 0.8.2, the function Message.check_instruct_content in metagpt/schema.py is vulnerable to deserialization via manipulation of the mapping argument. The attack requires local access.
Risk Assessment
A local attacker can execute arbitrary code via deserialization, leading to full system compromise. The project has not responded to the report.
Recommendation
Restrict local access to the system and monitor MetaGPT usage. Consider using alternative software until the vulnerability is patched.
