CVE-2004-1490
Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers.
Does this matter?
Lower severity and a low EPSS score (2.45%). Track it; it rarely justifies an emergency change on its own.
