Yesterday a widespread issue in OpenSSL was disclosed that would allow attackers to gain access to privileged information on any site running a vulnerable version of that software. Unfortunately, all Wikimedia Foundation hosted wikis are potentially affected. We have no evidence of any actual compromise to our systems or our users information, but as a precautionary measure we are resetting all user session tokens. In other words, we will be forcing all logged in users to re-login (ie: we are logging everyone out). All logged in users send a secret session token with each request to the site and if a nefarious person were able to intercept that token they could impersonate other users. Resetting the tokens for all users will have the benefit of making all users reconnect to our servers using the updated and fixed version of the OpenSSL software, thus removing this potential attack. As an extra precaution, we recommend all users change their passwords as well. Again, there has been no evidence that Wikimedia Foundation users were targeted by this attack, but we want all of our users to be as safe as possible.
