| VAR-202602-3024 | CVE-2026-27590 | Light Code Labs of Caddy Multiple vulnerabilities in |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
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 `strings.ToLower()` can change UTF-8 byte length for some characters. As a result, Caddy can derive an incorrect `SCRIPT_NAME`/`SCRIPT_FILENAME` and `PATH_INFO`, potentially causing a request that contains `.php` to execute a different on-disk file than intended (path confusion). In setups where an attacker can control file contents (e.g., upload features), this can lead to unintended PHP execution of non-.php files (potential RCE depending on deployment). Version 2.11.1 fixes the issue. Caddy was wrong `SCRIPT_NAME`/`SCRIPT_FILENAME` and `PATH_INFO` and the file on disk is different from the one you intended. RCE This issue can lead to 2.11.1 has been fixed.All information handled by the software may be leaked to the outside. All information handled by the software may be rewritten. Furthermore, the software may stop working completely. Furthermore, attacks that exploit this vulnerability will not affect other software
| VAR-202602-2870 | CVE-2026-27589 | Light Code Labs of Caddy Cross-site request forgery vulnerability in |
CVSS V2: - CVSS V3: 6.5 Severity: MEDIUM |
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 (`enforce_origin` not configured), the admin endpoint accepts cross-origin requests (e.g., from attacker-controlled web content in a victim browser) and applies an attacker-supplied JSON config. This can change the admin listener settings and alter HTTP server behavior without user intent. Version 2.11.1 contains a fix for the issue. HTTP You can change the server's behavior. 2.11.1 contains a fix for this issue.There is no risk of information being leaked to the outside world regarding the information handled by the software. However, there is a possibility that all information handled by the software may be rewritten. Furthermore, the software will not shut down.

CVSS V2: - CVSS V3: 9.1 Severity: CRITICAL |
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 host-based routing and any access controls attached to that route by changing the casing of the `Host` header. Version 2.11.1 contains a fix for the issue. This issue is fixed in version 2.11.1 has been fixed.All information handled by the software may be leaked to the outside. All information handled by the software may be rewritten. Furthermore, the software will not stop. Furthermore, attacks that exploit this vulnerability will not affect other software

CVSS V2: - CVSS V3: 9.1 Severity: CRITICAL |
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 attacker can bypass path-based routing and any access controls attached to that route by changing the casing of the request path. Version 2.11.1 contains a fix for the issue. 2.11.1 contains a fix for this issue.All information handled by the software may be leaked to the outside.

| VAR-202602-2836 | CVE-2026-27586 | Light Code Labs of Caddy Vulnerability in handling exceptional conditions in |
CVSS V2: - CVSS V3: 9.1 Severity: CRITICAL |
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 without error but accepts any client certificate signed by any system-trusted CA, completely bypassing the intended private CA trust boundary. Any deployment using `trusted_ca_cert_file` or `trusted_ca_certs_pem_files` for mTLS will silently degrade to accepting any system-trusted client certificate if the CA file becomes unavailable. This can happen due to a typo in the path, file rotation, corruption, or permission changes. The server gives no indication that mTLS is misconfigured. Version 2.11.1 fixes the vulnerability. All information handled by the software may be rewritten. Furthermore, the software will not stop. Furthermore, attacks that exploit this vulnerability will not affect other software
