Technical details
The vulnerability is an improper input validation flaw in Adobe Illustrator's file parsing mechanism. An attacker can craft a malicious file that bypasses input validation checks, leading to arbitrary code execution in the context of the current user. The attack requires user interaction—the victim must open the malicious file intentionally or be socially engineered to do so. The scope is changed, indicating the vulnerability can impact resources beyond the vulnerable component itself. A patch is expected to be available from Adobe via security bulletin APSB26-131.
