  "title": "caddy: Caddy is an extensible server platform that uses TLS by default",
  "description": "Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, the local caddy admin API (default listen \u0060127.0.0.1:2019\u0060) exposes a state-changing \u0060POST /load\u0060 endpoint that replaces the entire running configuration. When origin enforcement is not enabled (\u0060enforce_origin\u0060 not configured), the admin endpoint accepts cross-origin requests (e.g., from attacker-controlled web content in a victim browser) and applies an attacker-supplied JSON config. This can change the admin listener settings and alter HTTP server behavior without user intent. Version 2.11.1 contains a fix for the issue.",
