Tumblr Urges Users to Update iOS App, Password Amid Security Issue

Tumblr urged users to download an important update for its iOS apps on Tuesday, after a "security vulnerability" put passwords at risk.

"We have just released a very important security update for our iPhone and iPad apps addressing an issue that allowed passwords to be compromised in certain circumstances," Derek Gottfrid, the blogging platform's vice-president of product, said in a blog post. In a footnote, Gottfrid elaborated that passwords were "sniffed" or detected while in transit on certain versions of the app.

The company also advised users of its iOS apps to update their passwords on Tumblr, as well as "anywhere else you may have been using the same password."
