# CVE-2026-45692

## Summary

- **CVE ID:** CVE-2026-45692
- **Severity:** MEDIUM
- **CVSS Score:** 5.4 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N)
- **CWE:** CWE-187, CWE-863
- **Published:** Jun 23, 2026
- **Last Modified:** Jun 26, 2026

## Description

Caddy is an extensible server platform that uses TLS by default. From 2.4.0 until 2.11.3, the authorization layer and the /config traversal layer do not agree on what object the path refers to. In this case, a path authorized for one config object is accepted, but then resolves to a different config object during traversal. This happens because the authorization layer uses string prefix matching and the /config traversal layer parses array indices numerically using strconv.Atoi(). This vulnerability is fixed in 2.11.3.

## Affected Products

- caddyserver — caddy (>= 2.4.0, < 2.11.3)
