CVE-2020-15005
LOW3.1EPSS 0.74%mediawiki - security update
Published: 5/24/2022Modified: 4/28/2026
Description
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.
