+Subject: [PATCH 05/11] Fix GHSA-p99j-rfp4-xqvq
+
+It's no use trying to work around whatever the operating system and Apache
+do because we'll be fighting that until eternity.
+Change the skip_getopt condition such that when we're running in
+CGI or FastCGI mode we always skip the argument parsing.
+This is a BC break, but this seems to be the only way to get rid of this
+class of issues.
+
+(cherry picked from commit abcfd980bfa03298792fd3aba051c78d52f10642)
+(cherry picked from commit 2d2552e092b6ff32cd823692d512f126ee629842)
