Deeper analysis

CVE-2025-21159 is a Use After Free vulnerability (CWE-416) affecting Adobe Illustrator versions 29.1, 28.7.3, and earlier. The flaw occurs in the software and could result in arbitrary code execution in the context of the current user, with exploitation requiring user interaction such that a victim must open a malicious file.

The vulnerability carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Local attackers with low complexity can exploit it by tricking users into opening a specially crafted malicious file, achieving high-impact arbitrary code execution, confidentiality, integrity, and availability compromises under the privileges of the affected user.

Adobe's security bulletin APSB25-11 details the issue and recommends applying the available patches, as outlined at https://helpx.adobe.com/security/products/illustrator/apsb25-11.html.
