Electrum has released version 4.8.2, which includes multiple security fixes and enhances the security of the Bitcoin wallet codebase. These fixes are based on reports from researchers including the Bitcoin Red Team, Calle, l0rinc, haoxucu, and m0wer. This version addresses a critical backup issue affecting some Lightning wallets that use non-deterministic keys and anchored channels. Previously, affected wallets' channel backups and full wallet backups may have lacked the keys necessary to transfer funds on-chain after a remote force-close request. Affected users will receive a warning upon launching Electrum and should export a new backup, as old backups will not correctly restore funds in this scenario. Additionally, this version strengthens Lightning HTLC verification, rejects previously acceptable format errors for xpub/xprv keys, expands the scope of codebase security enhancements, and prevents Android QR code scanners from reading screenshots. This is the third security-focused release from Electrum since July, following versions 4.8.0 and 4.8.1.
