Summary
Craft CMS, a PHP content management system, has an arbitrary file read flaw in its app/icon-svg endpoint. A remote attacker with low-privilege control panel login can read SVG-format files readable by the PHP process, including files outside the Craft installation.
Read the original description
Craft CMS from 5.7.0 before 5.11.2 contains an arbitrary file read vulnerability that allows authenticated control panel users to read SVG files by posting arbitrary paths to the app/icon-svg endpoint. Attackers can supply aliases or absolute paths, which are resolved without permission checks, to read any SVG-content file readable by the PHP process, including files outside the Craft installation.
