Massive leak on Wikimedia sites
Posted: Wed Jul 16, 2025 7:55 am
Recently, I successfully managed to leak hundreds of gigabytes of sensitive information from Wikimedia sites. Including millions of deleted articles, tens of millions of deleted revisions, and (!!!) hundreds of thousands of overnighted revisions.
Given the sheer scale of the data, it's going to take me some time to release it all publicly. So far, I've created a demo for meta.wikimedia.org: https://unoversight.netlify.app/metawiki
In the coming weeks, I plan to release the rest of it. First English Wikipedia, then hopefully the rest of the WMF wikis.
