+Subject: [PATCH] Merge pull request from GHSA-cj83-2ww7-mvq7
+
+* fix: ReDoS in the `parse_http_accept_header` method
+
+Signed-off-by: Dwi Siswanto <git@dw1.io>
+
+* fix: optimize HTTP Accept headers parsing
+
+by:
+
+* updated `parse_http_accept_header` method to
+  avoid unnecessary array allocation from `map`.
+* used `strip!` to modify strings in place,
+  avoiding additional string allocations.
+* plus, safe navigation for `parameters` to
+  handle nil cases.
+
+this improves memory efficiency in header parsing.
