Good morning
could you align to the official NVD Nist cpe "foxitsoftware:foxit_reader"?
We would appreciate it very much.
Best regards,

Thank you. The official CPE dict is very chaotic: They randomly interchange "foxit" and "foxitsoftware" as vendor and "reader" and "foxit_reader" as software. We have normalized with a:foxitsoftware:foxit_reader:* as of now.
