Package        : mediawiki
CVE ID         : CVE-2020-15005 CVE-2020-25812 CVE-2020-25813 CVE-2020-25814
                 CVE-2020-25815 CVE-2020-25827 CVE-2020-25828

Multiple security issues were discovered in MediaWiki, a website engine
for collaborative work: SpecialUserRights could leak whether a user
existed or not, multiple code paths lacked HTML sanitisation allowing
for cross-site scripting and TOTP validation applied insufficient rate
limiting against brute force attempts.

For the stable distribution (buster), these problems have been fixed in
version 1:1.31.10-1~deb10u1.

We recommend that you upgrade your mediawiki packages.

For the detailed security status of mediawiki please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/mediawiki
