CVE ID : CVE-2020-25813 CVE-2020-25814 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.
