Adobe Illustrator

CVE-2026-21288

Illustrator versions 29.8.3, 30.0 and earlier are affected by a NULL Pointer Dereference vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to crash the application, causing disruption to services. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

What this means for your business

  • It affects Adobe Illustrator. 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, without a login, but only after tricking someone into an action such as opening a file or a link.

What to do

  1. 1Check whether your company or your suppliers run Adobe Illustrator, and which version. The affected versions are listed further down this page.
  2. 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
