caddy: Caddy is an extensible server platform that uses TLS by default
CVE-2026-45692 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-45692, released June 23, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
