0 CVE-2026-53965 is a medium severity vulnerability in the Model Context Protocol PHP SDK (mcp/sdk) versions 0.5.0 through 0.7.0. The HTTP client transport reads Server-Sent Events (SSE) streams into an unbounded in-memory buffer, which only flushes upon receiving a double newline delimiter. A malicious or compromised server that never sends this delimiter can cause the buffer to grow indefinitely, exhausting client memory and causing a denial of service. This affects any client using HttpTransport against an untrusted server and requires no authentication or user interaction beyond connection initiation. The issue is fixed in version 0.7.1.
