Name of the Vulnerable Software and Affected Versions
mcp-memory-service versions prior to 10.65.3
Description
The HTTP MCP JSON-RPC endpoint at "/mcp" fails to properly validate OAuth scopes. It allows requests with only the
read scope to be dispatched to handlers that include mutating tools. Consequently, a read-only OAuth client can execute store memory and delete memory functions through the MCP interface, bypassing the write scope requirement enforced on the corresponding REST endpoints.Recommendations
Update to version 10.65.3.
