[Electrum Releases 4.8.4 Security Update, Fixes Lightning Network Onion Message Vulnerability] Bitcoin wallet Electrum announced the release of version 4.8.4 on the X platform, calling it another security update. According to the GitHub changelog, the release date is November 6th, and it fixes a vulnerability related to Lightning Network onion messages: malformed onion messages from any source could cause Electrum to disconnect from its channel peers. Electrum will now discard all incoming onion messages until a real-world use case is implemented. In addition, the new version also fixes issues such as the failure to restore some mnemonic phrases from versions prior to 2.0. The previous Electrum version, 4.8.3, was released in late October, fixing a high-risk vulnerability that had been exploited in the wild.
