Уязвимость компонента img_auth.php программного средства для реализации гипертекстовой среды MediaWik, позволяющая нарушителю получить несанкционированный доступ к защищаемой информации

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.
