LONDON – Popular parenting website Mumsnet reported itself to the UK’s Information Commissioner. A bug that meant users’ accounts could potentially be switched was found. This meant people could have access to other’s account details and private messages. The company confirmed to the Guardian that it had reported itself, following the incident.
A botched upgrade to the software the forum runs on meant that for three days, if two users tried to log in at the same time, there was the possibility that their accounts would be switched. Each user was able to post as the other, see their account details, and read private messages. The company doesn’t know how many user accounts were affected, but says that over the three days the bug was live, from Tuesday afternoon to Thursday morning, about 4,000 users logged in. Of that, only 14 users have reported an issue.
