Tumblr has released a new update for their iOS app, the update comes in the form of a security update and Tumblr are advising users of the app to change their password.
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 circumstances¹. Please download the update now.
If you’ve been using these apps, you should also update your password on Tumblr and anywhere else you may have been using the same password. It’s also good practice to use different passwords across different services by using an app like 1Password or LastPass.
Please know that we take your security very seriously and are tremendously sorry for this lapse and inconvenience.
You can find out more details over at Tumblr.
