Alpine: multiple caddy packages: security update to 2.11.4-r0

low Tenable Cloud Security Plugin ID 443105

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Caddy is an extensible server platform that uses TLS by default. From 2.7.0 until 2.11.3, the FastCGI
 transport's splitPos() in modules/caddyhttp/reverseproxy/fastcgi/fastcgi.go misuses
 golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two
 distinct flaws in that fallback let an attacker mislead Caddy's FastCGI splitting into treating a non-.php
 (or other configured split_path extension) file as a script. In any deployment where the attacker can
 place content into a file served via FastCGI (uploads, file storage, etc.), this can be escalated to
 remote code execution by crafting a URL whose path triggers either flaw. This vulnerability is fixed in
 2.11.3. (CVE-2026-45135)

 - 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 caddy library and its related packages to version 2.11.4-r0 or later.
