kerframil 1535157341 learn In an (( arithmetic context )), never reference an array subscript dynamically as foo[$bar]. Instead, write foo[bar] for indexed arrays, and any of foo[\$bar], foo['$bar'] or ${foo[$bar]} for associative arrays. Otherwise, the expansion of $bar is repeated and is thus vulnerable to code injection.

Instead, write foo[bar] for indexed arrays, and any of foo[\$bar], foo['$bar'] or ${foo[$bar]} for associative arrays. Otherwise, the expansion of bar is repeated and is thus vulnerable to code injection. Bash-5.0 introduced an 'assoc_expand_once' shell option to protect against this issue.

kerframil 1610835153 learn In an arithmetic context, never specify the array subscript as an expansion in the manner of array[$key]. Instead, write array[key] for indexed arrays and array[\$key] for associative arrays. Otherwise, repeated expansions can occur, potentially leading to code injection. See also !assoc_expand_once and !pf 45.

Alas, as of bash 5.2, the [\$key] method no longer works and should now be avoided to ensure forward

tirnanog 1670935558 learn In an arithmetic context, never specify an array subscript as array[$key] for arbitrary values of $key. Instead, write array[key] for indexed arrays and array[\$key] for associative arrays, to avoid code injection. Alas, as of bash 5.2, the [\$key] method no longer works and should be avoided to ensure forward compatibility. See, also, !pf 45, !pf 62 and !assoc_expand_once.
