CVE-2026-92284: Caddyserver Caddy

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

Caddy is an extensible server platform that uses TLS by default. In version 2.11.3 and earlier, in modules/caddyhttp/replacer.go, resolving http.request.body reads the complete request body with an unbounded io.Copy before request-body middleware limits apply, allowing memory exhaustion and process termination.

Affected products

• Caddyserver Caddy: up to and including 2.11.3
