When .automated_script.sh parses "script=" kernel command line parameter it uses longest prefix substitution for variable expansion:
echo "${param##*=}"
For HTTP urls containing GET request parameters this leads to incorrect expansion on "=" symbol boundary.
Changing expansion to "${param#*=}" fixes this issue:
$ param="script=http://domain.tld/path/script?id=1&param=2" && echo "${param##*=}"
2
$ param="script=http://domain.tld/path/script?id=1&param=2" && echo "${param#*=}"
http://domain.tld/path/script?id=1&param=2
