SCA: security update for github.com/caddyserver/caddy/v2 (GHSA-x5w9-xh9r-mvfc)

low Tenable Self-Hosted Container Security Plugin ID 442157

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-45692)

Solution

Update the github.com/caddyserver/caddy/v2 library and its related packages to version 2.11.3 or later.
