A WHATSAPP user has claimed that she's able to see someone else's messages in her own app.

The alleged bug means a random person's private texts may have been exposed to a complete stranger.

This particular fail was spotted by Abby Fuller, an Amazon employee who works at the company's Amazon Web Services division.

She complained about the bug on Twitter, saying "this doesn't seem right".

"Logged into WhatsApp with a new phone number today and the message history from the previous number's owner was right there?!

"And now I'm wondering how many other times it's happened? Like does whoever has my old number now have MY WhatsApp history?"

Fellow Twitter users were quick to bombard her with questions – to see if she'd done something wrong, or to work out an explanation.

She replied: "Yes it was a new device. No it wasn't second hand. It was not a second-hand SIM."

"Yes I'm sure they weren't my messages, or groups that I was added to.

"Yes they were in plaintext. I am sure it's my phone number. It was not restored from a backup," Fuller added.

For now, this appears to be an isolated incident – no one else seems to have complained about a similar gaffe.

But it's seriously worrying if people who take your old number are able to access your message history.

We've asked WhatsApp for comment and will update this story with any response.

WhatsApp users are being warned about infamous WhatsApp Gold malware spreading through the app

WhatsApp was recently accused of creating another bug on the app too.

A number of users have complained that WhatsApp has been mysteriously deleting their messages – seemingly at random.

Some users report the glitch is killing off messages from 2015 or earlier, while others claim chats from last year are vanishing.

Watch out for the infamous WhatsApp Gold virus scam that's being doing the rounds on the app.

And don't fall for a WhatsApp free plane tickets scam either.

And get excited for the upcoming WhatsApp Vacation Mode, which should make your holidays much more relaxing.
