Detailsinfo

A vulnerability was found in doobidoo mcp-memory-service up to 10.67.0 and classified as critical. Affected by this issue is an unknown part of the file /api/documents. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

mcp-memory-service is a semantic memory layer for AI applications. Prior to 10.67.1, all HTTP routes under /api/documents/* in mcp-memory-service are served without any authentication dependency, even when the server is configured with an API key (MCP_API_KEY) or OAuth. An unauthenticated remote attacker can upload arbitrary content into the memory store (write), retrieve stored document content (read), and permanently delete memories belonging to authenticated users (delete) — all without supplying any credentials. The /api/memories counterpart correctly enforces authentication, making this an inconsistent and exploitable authentication boundary. This vulnerability is fixed in 10.67.1.

The advisory is shared for download at web.archive.org. This vulnerability is handled as CVE-2026-50027 since 06/03/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available.
