## Technical details

A policy bypass vulnerability exists in ImageMagick's Magick.NET library due to an incomplete fix for a previous security issue. The flaw involves improper link resolution (CWE-59) and a time-of-check time-of-use (TOCTOU) race condition (CWE-367). A local attacker with low privileges can exploit these weaknesses to bypass authorization checks and access unintended resources. The vulnerability is triggered when the product attempts to access a file without properly preventing the filename from resolving to a symbolic link or shortcut. This issue is addressed in Magick.NET version 14.15.0.
