SUSE CVE-2026-27585

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, the path sanitization routine in file matcher doesn't sanitize backslashes which can lead to bypassing path related security protections. It affects users with specific Caddy and environment configurations...

SUSE CVE-2026-27586

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, two swallowed errors in ClientAuthentication.provision cause mTLS client certificate authentication to silently fail open when a CA certificate file is missing, unreadable, or malformed. The server starts...

SUSE CVE-2026-27587

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, 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...

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...

SUSE CVE-2026-27589

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, the local caddy admin API default listen 127.0.0.1:2019 exposes a state-changing POST /load endpoint that replaces the entire running configuration. When origin enforcement is not enabled enforceorigin not...

SUSE CVE-2026-27590

Caddy is an extensible server platform that uses TLS by default. Prior to version 2.11.1, 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...
