On Friday, September 26, the system hackers team discovered a misconfiguration in the wiki setup. The error, if discovered, would have enabled an unauthorised party to read protected pages and user configurations.
It was possible to read the encrypted password hashes of guest users. Registered Fellows, who log in using their Fellowship password were not affected by this. To all others we recommend changing their wiki password as a precaution.
