Google Play Services SDK: Trust Boundary Violation

CVE-2022-1799 is a critical-severity trust boundary violation vulnerability in Google Play Services SDK from Google, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 18.0.2 as the first without the flaw, so updating Google Play Services SDK to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.31% chance of exploitation within 30 days, which is low compared with other CVEs.
