CVE-2026-86422
ImageMagick before 7.1.2-30 contains a time-of-check-time-of-use vulnerability in path policy enforcement on Windows that allows attackers to bypass read or write restrictions by exploiting symlink race conditions. Attackers can swap symlinks between policy validation and file access to read or write policy-denied files.
What this means for your business
- It affects Imagemagick. It matters if your company, or a supplier that handles your data, runs it.
- An attacker can use it only with access to the machine itself, with an ordinary user login, but only after tricking someone into an action such as opening a file or a link.
What to do
- 1Check whether your company or your suppliers run Imagemagick, and which version. The affected versions are listed further down this page.
- 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
