Apple today released watchOS 7.3.3, a security-centric update for the Apple Watch. watchOS 7.3.3 comes three weeks after the release of watchOS 7.3.2.
watchOS 7.3.3 can be installed on a compatible Apple Watch via the Watch app on the device’s attached iPhone. Go to “General” -> “Software Update” to install the new software. The Watch should have at least 50% battery life, be connected to a charger, and be in the range of the iPhone.
The software provides important security fixes and should be installed by all users. An Apple security support document says that the watchOS 7.3.3 update addresses a vulnerability that was actively exploited.
Impact: Processing maliciously crafted web content may lead to universal cross site scripting. Apple is aware of a report that this issue may have been actively exploited.
This exploit may be out in the wild, so Apple Watch owners should update their wearables as soon as possible.
