FKIE_CVE-2020-15005

Vulnerability from fkie_nvd - Published: 2020-06-24 23:15 - Updated: 2026-06-17 02:55
Severity
3.1 (Low) - CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N
Summary
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.
