NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-github-go-chi-chi package and not the golang-github-go-chi-chi package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

go-chi chi before 5.5.0 contains an authentication bypass in middleware.SupressNotFound, which calls Match with the live routing context and leaves a mounted router's parameter and child suffix in place for dispatch against the outer router. Unauthenticated attackers can request a mounted path whose suffix matches an outer public route, skipping the mounted authentication middleware and retrieving tenant-scoped data when that outer handler trusts the retained mount parameter.
