I would like to announce the release of MediaWiki 1.20.5 and 1.19.6. These releases fix 2 security related issues that could affect users of MediaWiki. Download links are given at the end of this email.

* Jan Schejbal / Hatforce.com reported that SVG script filtering could be bypassed for Chrome and Firefox clients by using an encoding that MediaWiki understood, but these browsers interpreted as UTF-8. https://bugzilla.wikimedia.org/show_bug.cgi?id=47304

* Internal review discovered that extensions were not given the opportunity to disable a password reset, which could lead to circumvention of two-factor authentication. https://bugzilla.wikimedia.org/show_bug.cgi?id=46590
