Critical Vulnerability in Samsung One UI Exposes Sensitive Information in Plain Text

Critical Vulnerability in Samsung One UI Exposes Sensitive Information in Plain Text


Samsung One UI users reported a critical vulnerability in the smartphone’s interface, where the clipboard history saves and stores all copied information in plain text, including personal information like passwords.

A recent discussion in Samsung’s community forum highlights users’ frustration with the company’s inability to address the issue. After all, security vulnerabilities related to the clipboard function of Samsung smartphones have been reported as far back as 2014. For now, the only solution is manually clearing the clipboard to avoid exposing critical data.

Security flaw alert on mobile

All copied data is exposed indefinitely

Samsung One UI’s clipboard history retains everything you copy indefinitely, which means that passwords, banking information, and PINs copied to make navigation easy essentially put users at risk.

Users who tried to fix this issue by using a third-party keyboard discovered that there’s no loophole tactic or workaround until Samsung fixes it. In the meantime, Samsung urges users to regularly clear the clipboard history and exercise caution when copying critical information.

The importance of securing sensitive information

Considering that 2025 might be the worst year for cybersecurity, this type of security flaw is appalling. Users should be extremely careful when handling sensitive data and aim to share it only in strictly necessary environments, such as login forms.

We’ve outgrown the need to rely on memory, written notes, or notepad documents to remember that type of information, and that’s why we recommend using a password manager. Most solutions allow you to easily and quickly fill in login forms while guaranteeing that all data is encrypted.

How can password managers help?

1

Secure autofill: Guarantees encryption when filling out forms.

2

Strong passwords: Helps generate unique and long passwords for each account.

3

One password only: Frees up your memory since you only have to memorize one or two master passwords.
