CVE-2026-33010
MCP (Model Context Protocol) · mcp-memory-service
A high-severity vulnerability in the mcp-memory-service, an open-source memory backend for multi-agent systems, could lead to unauthorized memory access or data leakage.
Executive summary
A security flaw in the mcp-memory-service could allow attackers to access or manipulate the memory state of AI agents, compromising the integrity of multi-agent systems.
Vulnerability
The mcp-memory-service contains a vulnerability in its memory backend management. With a CVSS score of 8.1, the flaw likely permits unauthorized retrieval or modification of stored context in AI systems, potentially allowing an attacker to influence agent behavior or extract sensitive information from the agent's memory.
Business impact
Exploitation could lead to the exposure of sensitive data handled by AI agents or the "poisoning" of agent memory to cause incorrect or malicious actions. This poses a significant risk to organizations deploying multi-agent AI systems, as it directly impacts the reliability and confidentiality of automated processes.
Remediation
Immediate Action: Apply the latest security updates to the mcp-memory-service and review access control policies for the memory backend.
Proactive Monitoring: Audit memory access logs for unusual retrieval patterns or unauthorized attempts to write to the memory service from unknown agents.
Compensating Controls: Implement strong authentication and encryption for all communications between AI agents and the memory service.
Exploitation status
Public Exploit Available: false
Analyst recommendation
Immediate patching of the mcp-memory-service is essential to protect the integrity of AI-driven workflows. Organizations should ensure that only authorized agents can access the memory service and that all stored data is protected against unauthorized tampering.
