Title: MediaWiki Exposure of Sensitive Information to an Unauthorized Actor Vulnerability
Overview:

In MediaWiki before 1.31.8 1.32.x and 1.33.x before 1.33.4 and 1.34.x before 1.34.2 private wikis behind a caching server using the img_auth.php image authorization security feature may have had their files cached publicly so any unauthorized user could view them. This occurs because Cache-Control and Vary headers were mishandled.
