SCA: security update for github.com/caddyserver/caddy/v2 (GHSA-m675-2p33-xv9g)

high Tenable Cloud Security Plugin ID 442061

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 2.7.0 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)

Solution

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