CVE-2015-2940
Cross-site request forgery (CSRF) vulnerability in the CheckUser extension for MediaWiki allows remote attackers to hijack the authentication of certain users for requests that retrieve sensitive user information via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (1.09%). Track it; it rarely justifies an emergency change on its own.
