Upgrade Minimos:latest paketo-buildpacks-pipenv-install-0.7.39 to version 0.7.39-r1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream paketo-buildpacks-pipenv-install-0.7.39 package and not the paketo-buildpacks-pipenv-install-0.7.39 package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, the xDS RBAC HTTP filter in internal/xds/httpfilter/rbac/rbac.go does not lowercase header matcher names in normalizeHeaderMatcher even though incoming metadata keys are lowercase. A DENY policy using a mixed-case name such as X-Role or User-Agent therefore does not match and fails open, allowing requests that should be rejected. The same case mismatch permits :Scheme or Grpc-Status to evade gRFC A41 validation and prevents Host from being rewritten to :authority. This issue is fixed in version 1.83.1.
