Does this matter?
Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.
Description
paymentrequest.py in Electrum before 4.2.2 allows a file:// URL in the r parameter of a payment request (e.g., within QR code data). On Windows, this can lead to capture of credentials over SMB. On Linux and UNIX, it can lead to a denial of service by specifying the /dev/zero filename.
