Sparrow Wallet Releases Version 2.5.4, AI-Assisted Code Review Fixes Multiple Security Vulnerabilities
According to Decrypt, privacy-focused Bitcoin wallet Sparrow Wallet released version 2.5.4 on August 28. Developer Craig Raw stated that the update was driven by an AI-assisted code review, with the majority of fixes originating from it. This review was prompted by the recent seed generation code vulnerability exploit affecting Coldcard, as well as the release of unrestricted AI models in China, which has significantly enhanced vulnerability scanning capabilities across large codebases. Key updates include: validating the authenticity of transactions returned by Electrum servers, enforcing stricter BitBox02 hardware wallet security requirements (firmware v9.4.0 or higher required), patching local DNS leaks, and masking sensitive credentials in debug logs. Raw noted that there are no indications of any exploits being leveraged, user funds remain secure, and he still advises all users to update at their earliest convenience.
