Race Condition

Overview Affected versions of this package are vulnerable to Race Condition in the handle process due to the sync.RWMutex being released before L.Push and L.PCall execute. An attacker can cause Lua VM corruption or unpredictable server behavior by making concurrent requests that race on the share...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal via the Host header when the server is running in --domain mode.

CVE-2026-45721

Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, when Algernon is asked for any URL path that resolves to a directory without an index file, DirPage walks upward through parent directories — past the configured server root — looking for a file named handler.lua to execute a...

CVE-2026-45728

Algernon is a small self-contained pure-Go web server. Prior to 1.17.7, when Algernon is invoked with a single file path instead of a directory, singleFileMode is set to true and debugMode is forcibly enabled. debugMode activates the PrettyError renderer, which on any Lua or template error respon...

CVE-2026-43981

Algernon is a small self-contained pure-Go web server. Prior to 1.17.6, in engine/luahandler.go, the sync.RWMutex protecting LoadCommonFunctions is released before L.Push and L.PCall execute. Since gopher-lua's LState is explicitly not goroutine-safe, concurrent requests race on the shared state...

CVE-2026-23631
