      <title>CVE-2026-30852 — Caddy: vars_regexp double-expands user input, leaking env vars and files</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-30852</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; caddyserver caddy&lt;/p&gt;
&lt;p&gt;Caddy is an extensible server platform that uses TLS by default. From version 2.7.5 to before version 2.11.2, the vars_regexp matcher in vars.go:337 double-expands user-controlled input through the Caddy replacer. When vars_regexp matches against a placeholder like {http.request.header.X-Input}, the header value gets resolved once (expected), then passed through repl.ReplaceAll() again (the bug). This means an attacker can put {env.DATABASE_URL} or {file./etc/passwd} in a request header and the server will evaluate it, leaking environment variables, file contents, and system info. This issue has been patched in version 2.11.2.&lt;/p&gt;</description>
