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...

PT-2026-22069

Name of the Vulnerable Software and Affected Versions Go MCP SDK versions prior to 1.3.1 Description The Go MCP SDK used Go's standard encoding/json.Unmarshal for JSON-RPC and MCP protocol message parsing. Go's standard library performs case-insensitive matching of JSON keys to struct field tags,...

MCP Go SDK 安全漏洞

MCP Go SDK is an open-source development toolkit for the Model Context Protocol. Versions of the MCP Go SDK prior to 1.3.1 contained security vulnerabilities. These vulnerabilities stemmed from the use of case-insensitive JSON key matching during the parsing of JSON-RPC and MCP protocol messages,...

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...

Improper Handling of Case Sensitivity

Overview Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity in the host request matcher when the host list contains more than 100 entries. An attacker can gain unauthorized access to protected routes and sensitive endpoints by altering the case of the Host...

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...

Improper Handling of Case Sensitivity

Overview Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity in the matchPatternWithEscapeSequence function when handling patterns containing percent-escape sequences. An attacker can gain unauthorized access to protected routes and sensitive endpoints by...

Caddy: MatchPath %xx (escaped-path) branch skips case normalization, enabling path-based route/auth bypass

Summary Caddy's HTTP path request matcher is intended to be case-insensitive, but when the match pattern contains percent-escape sequences %xx it compares against the request's escaped path without lowercasing. An attacker can bypass path-based routing and any access controls attached to that rou...
