Official Description
Improper handling of symbolic links in the installer of My Image Garden for macOS Version 3.6.8 or earlier may allow a local attacker with login privileges to exploit a specially crafted symbolic link during installation to modify permissions of files for which they would not normally have authorization.
Technical Analysis
CVE-2026-6891 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in full integrity compromise (data manipulation), with a CVSS base score of 5.0.
