Security

This page documents information related to MediaWiki security.

Report a security problem
If you have found or believe you have found a security bug in MediaWiki or on one of Wikimedia's web sites, please directly e-mail security&#64;wikimedia.org with details.
 * Emailing the details to that address ensures that the issue is dealt with quickly and with the best outcome for our third-party users. Please do not report the issue directly in Bugzilla UNLESS you use the "Security" component, which ensures the bug is not publicly readable.
 * See Reporting security bugs for more information about the process.

We would be most happy to have a day or two to fix the problem and prepare a bug fix for third-party users before public disclosure, if possible.

(Note that any security problems found in the wiki-to-HTML parser will be included in the parser regression test suite in the next release.)
