Electrum has issued version 4.8.3 to address a critical security vulnerability, urging all users to upgrade immediately. The team said a description of the vulnerability would be published later the same day, alongside a disclosure link. The release notes also flag a Windows Defender warning about ZXing.dll, which the developers say is a false positive and can be ignored. No technical details of the flaw were included in the announcement itself.
