According to CoinMeta, security researchers are warning iPhone users that there may be a Safari zero-day vulnerability, which could expose sensitive data such as cryptocurrency private keys and mnemonics. The report indicates that this attack involves a chain of vulnerabilities based on Safari, and could progress from memory corruption in WebKit / JavaScriptCore to sandbox escape and kernel-level access. The warning applies to iOS versions ranging from 13 to 26.5, although the full range has not yet been independently confirmed. It is recommended that iPhone users check for the latest iOS updates and install them as soon as possible, while also avoiding opening untrusted links in Safari, especially if you store encrypted wallet data on your device.
