can you please let me know in which version of wiki we have fixed the Heartbleed bug..
Topic on Project:Support desk
MediaWiki does not have Heartbleed bug because it doesn't use any openssl component. Openssl components are part of the operating system, both the server and the client, if you're connecting through HTTPS
MediaWiki code itself was never affected. Also see https://blog.wikimedia.org/2014/04/10/wikimedias-response-to-the-heartbleed-security-vulnerability/
