NVD · uneditedImproper access control vulnerability in Samsung Account prior to version 14.5.01.1 allows attackers to access sensitive information via implicit intent.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceImproper access control in Samsung Account versions before 14.5.01.1 allows malicious apps to intercept sensitive information through implicit intents. The app exposes components that do not properly validate incoming intent sources, enabling unauthorized access to user data.
