CVSS 3.1
3.1 lowCVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:NCVE-2020-15005
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.
