Algernon: Auto-refresh SSE event server binds to all interfaces by default on Linux/macOS

Summary The SSE event server bound to 0.0.0.0:5553 on Linux/macOS by default because the platform-dependent host default in engine/flags.go:39-46 set host = "" for non-Windows, and utils.JoinHostPort"", ":5553" resolves to ":5553" — a Go http.Server.Addr of ":5553" listens on every interface. On...

Algernon: Auto-refresh SSE event server binds to all interfaces with Access-Control-Allow-Origin: * and no authentication

Summary When auto-refresh is enabled, Algernon spins up an SSE handler that streams a data: line for every filesystem event under the watched directory. The handler performs no authentication of any kind — no shared token, no cookie check against the permissions2 userstate, no IP allow-list, no...

CVE-2026-43968

A flaw was found in cowlib. An Improper Neutralization of CRLF Sequences Carriage Return Line Feed Injection vulnerability allows a remote attacker to inject bare carriage return characters into Server-Sent Events SSE fields. This enables event splitting and injection of arbitrary event types and...
