@cpakulski anything with backport/review label needs to be evaluated for backporting and if approved, that label should be changed to backport/approved and PRs sent to stable releases.

The fix has been backported to 1.16, 1.15 and 1.14. Release 1.13 do not use pauseListening, resumeListening and shutdownListener methods, which this PR fixed and therefore the changes were not backported.

* [v1.15] http: header map security fixes for duplicate headers (#197) (#200)

Previously header matching did not match on all headers for
non-inline headers. This patch changes the default behavior to
always logically match on all headers. Multiple individual
headers will be logically concatenated with ',' similar to what
is done with inline headers. This makes the behavior effectively
consistent. This behavior can be temporary reverted by setting
the runtime value "envoy.reloadable_features.header_match_on_all_headers"
to "false".

Targeted fixes have been additionally performed on the following
extensions which make them consider all duplicate headers by default as
a comma concatenated list:
1) Any extension using CEL matching on headers.
2) The header to metadata filter.
3) The JWT filter.
4) The Lua filter.
Like primary header matching used in routing, RBAC, etc. this behavior
can be disabled by setting the runtime value
"envoy.reloadable_features.header_match_on_all_headers" to false.

Finally, the setCopy() header map API previously only set the first
header in the case of duplicate non-inline headers. setCopy() now
behaves similiarly to the other set*() APIs and replaces all found
headers with a single value. This may have had security implications
in the extauth filter which uses this API. This behavior can be disabled
by setting the runtime value
"envoy.reloadable_features.http_set_copy_replace_all_headers" to false.
