CVE-2026-27896

The Go MCP SDK used Go's standard encoding/json.Unmarshal for JSON-RPC and MCP protocol message parsing in versions prior to 1.3.1. Go's standard library performs case-insensitive matching of JSON keys to struct field tags — a field tagged json:"method" would also match "Method", "METHOD", etc...

CVE-2026-27896

The CVE-2026-27896 concerns the Go MCP SDK, affected in versions prior to 1.3.1, where Go’s json.Unmarshal (case-insensitive field matching) could accept non-standard JSON-RPC/MCP field casing. This violates JSON-RPC 2.0’s exact field names and could allow messages to bypass intermediary inspecti...

SUSE CVE-2026-27588

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, Caddy's HTTP host request matcher is documented as case-insensitive, but when configured with a large host list 100 entries it becomes case-sensitive due to an optimized matching path. An attacker can bypass...

GHSA-5R3V-VC8M-M96G Caddy: Unicode case-folding length expansion causes incorrect split_path index in FastCGI transport

Summary Caddy's FastCGI path splitting logic computes the split index on a lowercased copy of the request path and then uses that byte index to slice the original path. This is unsafe for Unicode because strings.ToLower can change UTF-8 byte length for some characters. As a result, Caddy can deri...

Caddy: MatchHost becomes case-sensitive for large host lists (>100), enabling host-based route/auth bypass

Summary Caddy's HTTP host request matcher is documented as case-insensitive, but when configured with a large host list 100 entries it becomes case-sensitive due to an optimized matching path. An attacker can bypass host-based routing and any access controls attached to that route by changing the...
