AI Security Incident
### Summary In affected versions, a Streamable HTTP server in stateful mode (the default) never reclaimed session state: - sessions did not expire; - a client `DELETE` ended the session but left its entry registered; - a session whose first request was refused stayed registered with a running task. Each session also kept its parsed `initialize` parameters, and the number of sessions was unlimited. A client that could reach the endpoint could grow server memory without bound using ordinary short requests; only a restart reclaimed it. ### Am I affected? Yes, if you serve MCP over Streamable HTTP in stateful mode and clients you do not fully trust can reach the endpoint. Stateful mode is the default for: - `FastMCP` (1.x) - `MCPServer` and `Server.streamable_http_app()` (2.x) - `StreamableHTTPSessionManager` Affected versions: 1.8.0 through 1.29.1, and 2.0.0 through 2.1.1. Not affected: - servers on 1.12.0 or later passing `stateless_http=True` (no sessions are kept) - servers using only the stdio or SSE transports Authentication limits who can open sessions, not how many a token holder can open. ### Fix Upgrade to `mcp` 1.30.0 (1.x) or 2.2.0 (2.x) or later. In those versions: - a session with no request in flight for `session_idle_timeout` seconds (default 1800) is closed and its ID then answers `404`; open streams and in-progress requests keep it alive; - at most `max_sessions` sessions exist at once (default 10000); a request that would open another is answered `503`; - a session is discarded as soon as it ends, whether by `DELETE`, expiry, or a refused opening request. Both settings are keyword arguments on `FastMCP(...)` (1.x), `MCPServer.run()` / `streamable_http_app()` (2.x) and `StreamableHTTPSessionManager`; `None` disables them. This bounds retention rather than eliminating it: a live session still holds its `initialize` parameters (up to roughly twice the 4 MiB body limit), and an `initialize` with invalid parameters still opens a session that ex
FBI Arrests Another Data Exposure

Attackers Use Malicious Terraform Providers to Deliver Go Malware via HashiCorp Registry
Cybersecurity researchers have disclosed Go-based malware distributed via two Go Modules and two Terraform providers, marking the first time threat actors are using the centralized repository hosted by HashiCorp as a distribution vector for malicious payloads. According to Aikido, the list of Terraform providers and Go modules is below - gocommunity-io/dockerd (222 downloads) kreuzwenker/

OpenAI Supply-Chain Compromise
The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the
