img_auth.php may leak private extension images into the public cache
Quick fix
GHSA-xpv7-93cm-4mxv — mediawiki/core: upgrade to the fixed version with the command below.
composer require mediawiki/core:^1.31.8Details
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.
