Detailsinfo

A vulnerability, which was classified as problematic, was found in doobidoo mcp-memory-service up to 10.65.2. This affects an unknown function of the component HTTP MCP JSON-RPC Endpoint. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on integrity, and availability. The summary by CVE is:

mcp-memory-service is a semantic memory layer for AI applications. Prior to version 10.65.3, the HTTP MCP JSON-RPC endpoint at `/mcp` requires only OAuth `read` scope for all requests, then dispatches `tools/call` directly to handlers that include mutating tools. A read-only OAuth client can call `store_memory` and `delete_memory` through MCP even though the corresponding REST endpoints require `write` scope. Version 10.65.3 patches the issue.

The advisory is shared at web.archive.org. This vulnerability is uniquely identified as CVE-2026-49291 since 05/28/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Neither technical details nor an exploit are publicly available.
