Name of the Vulnerable Software and Affected Versions MediaWiki versions 1.37.x before 1.37.2

Description A denial-of-service issue was discovered. The rendering of "w/index.php?title=Special:WhatLinksHere&target=Property:P31&namespace=1&invert=1" can take more than thirty seconds, posing a DDoS risk.
