On October 1, 2013, we learned about an implementation error that made
private user information (specifically, user email addresses, password
hashes, session tokens, and last login timestamp) for approximately
37,000 Wikimedia project users accessible to volunteers with access to
the Wikimedia "LabsDB" infrastructure.
LabsDB, launched in May 2013, is designed to give volunteers the
ability to write tools and generate reports that make use of data from
our databases in real-time. This supports bottom-up innovation by the
Wikimedia community. As part of this process, private data is
automatically redacted before volunteers are given access to the data.
Unfortunately, for some of Wikimedia’s wikis[1], the database triggers
used to redact private data failed to take effect due to a schema
incompatibility, and LabsDB users had access to private user data for
some user accounts in these specific wiki databases. As of October 1,
228 users have access to LabsDB, and the window of availability of
this data was May 29, 2013 to October 1, 2013.
This issue was discovered and reported by a trusted volunteer, and
access to the data in question was revoked within 15 minutes of the
report. We have no evidence to suggest that the private data in
question was exported in bulk or used for malicious purposes, but we
cannot definitively exclude the possibility. As a precautionary
measure, we have invalidated all affected user sessions, and are
requiring affected users to change their password on their next login.
We have also sent an email notification to affected users with a
confirmed email address.
We regret this mistake. LabsDB is still a new part of our
infrastructure, and we will fully audit the redaction process, so as
to minimize any risk of a future mistake of this nature.
Sincerely,
Erik Moeller
Vice President of Engineering & Product Development
