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.

Affected configurations

• mediawiki mediawiki (< 1.31.8) • mediawiki mediawiki (>= 1.32.0 < 1.33.4) • mediawiki mediawiki (>= 1.34 < 1.34.2) • fedoraproject fedora 32 • debian debian linux 9.0 • debian debian linux 10.0
