CVE-2026-46430
Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, 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"...
CVE-2026-44214
eventsource-encoder encodes events as well-formed EventSource/Server Sent Event SSE messages. Prior to 1.0.2, eventsource-encoder does not sanitize the event or id fields of an EventSourceMessage before serializing them. An attacker who controls either field can inject arbitrary Server-Sent Event...

CVE-2026-44830 Empty API_TOKEN disables authentication on network-reachable HTTP/SSE transport
Nocturne Memory is a lightweight, rollbackable, and visual Long-Term Memory Server for MCP Agents. Prior to 2.4.1, when APITOKEN is unset or empty, the BearerTokenAuthMiddleware bypasses authentication for all HTTP requests. Combined with the default 0.0.0.0 host binding and CORS alloworigins="",...

CVE-2026-46431
Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, the SSE event server's Access-Control-Allow-Origin response header was hardcoded to the wildcard regardless of the caller's Origin. Because EventSource does not preflight and does not send cookies, the wildcard is sufficient ...
algernon 安全漏洞
Algernon is a web server developed by Alexander F. Rødseth. Versions of Algernon prior to 1.17.7 contained a security vulnerability. This vulnerability stemmed from the hardcoded wildcard in the Access-Control-Allow-Origin header of the SSE event server, which could allow any third-party page to...
