Published Updated By the CyberSecBulletin desk

CVE-2022-39869 is a high-severity exposure of resource to wrong sphere vulnerability in SmartThings from Samsung, with a CVSS 3.1 base score of 7.5 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 1.7.89.0 as the first without the flaw, so updating SmartThings to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.41% chance of exploitation within 30 days, which is low compared with other CVEs.
