  "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 2.11.4, Caddy\u2019s stripHTML template function cannot reliably remove all HTML tags from input strings. Certain malformed HTML, such as \u003C\u003C\u003Eimg src=x onerror=alert()\u003E, can bypass the tag-stripping logic, potentially leaving dangerous content in the output if it is later rendered as HTML. This may allow client-side XSS in cases where untrusted strings are rendered unsafely. This vulnerability is fixed in 2.11.4.",
