CVE-2026-48126 Algernon: Host header path traversal in --domain mode reads files and runs Lua from parent dir
Algernon is a small self-contained pure-Go web server. Prior to 1.17.8, when algernon is started with --domain or --letsencrypt, which silently turns on --domain at engine/flags.go:372, the request handler resolves the served directory by joining the configured --dir with the value of the...
CVE-2026-48126
Algernon, a small self-contained pure-Go web server, is vulnerable prior to version 1.17.8 when started with --domain (or --letsencrypt). The request handler resolves the served directory by joining the configured --dir with the client-supplied Host header using filepath.Join without validation, ...

CVE-2026-46431
CVE-2026-46431 affects Algernon’s SSE event server prior to version 1.17.7, where Access-Control-Allow-Origin was hardcoded to “*”. This allowed cross-origin EventSource connections to read the live filename stream, compromising confidentiality. The issue is fixed in 1.17.7; upgrading to that ver...
CVE-2026-46431 Algernon: Auto-refresh SSE event server sets Access-Control-Allow-Origin: *
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 ...

CVE-2026-46430 Algernon: Auto-refresh SSE event server binds to all interfaces by default on Linux/macOS
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-2026-46430
CVE-2026-46430 affects Algernon (SSE event server). Before 1.17.7, the SSE event server bound to 0.0.0.0:5553 by default on Linux/macOS due to host default logic, enabling LAN-wide access. The issue arises from platform-dependent default host handling (empty on non-Windows), resulting in an effec...

CVE-2026-45728 Algernon: Single-file mode unconditionally enables debug mode
Algernon is a small self-contained pure-Go web server.

CVE-2026-45728 (Algernon) exposes server-side source on error when running in single-file mode. Prior to 1.17.7, invoking Algernon with a file path (not a dir) forces singleFileMode, which enables debugMode and renders PrettyError pages that reveal the absolute path and full contents of the error...
