UserVoice learned in late April that an unauthorized party illegally accessed one of UserVoice’s backend reporting systems and was able to view user data on a small subset of users.
The user data included name, email, and a hashed password and salt.
Unfortunately, the passwords were hashed with the SHA1 hashing algorithm.
The company reset the passwords for the users whose information was accessed and contacted them directly.
