Adobe has rolled out a crucial security patch for Illustrator, its widely-used graphic design tool, to address a serious flaw that could enable attackers to run malicious code on affected machines.
The update specifically targets a heap-based buffer overflow vulnerability, impacting various versions of Illustrator on both Windows and macOS operating systems.
Labeled as CVE-2025-30330, this vulnerability carries a critical severity rating, with a CVSS base score of 7.8. Security experts have classified it under the heap-based buffer overflow category (CWE-122), which poses a significant risk, potentially allowing attackers to gain full control over a system if exploited.
According to Adobe’s official security advisory, “An attacker could exploit this flaw to execute arbitrary code within the context of the currently logged-in user.”
The security risk is characterized by the CVSS vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating that local access is needed, and if exploited, it could severely impact the confidentiality, integrity, and availability of the system.
Experts note that for an attacker to take advantage of this vulnerability, user interaction is necessary. The victim must open a malicious file that the attacker has carefully crafted. Such attacks typically occur via infected Illustrator files distributed through email, compromised websites, or other delivery methods.
An attacker could lure the victim into opening a malicious file, causing the buffer overflow and enabling them to execute harmful code on the system.
This vulnerability was discovered by a security researcher known as “yjdfy,” who reported the issue to Adobe.
Affected Versions:
- Illustrator 2025 (version 29.3 and earlier) on both Windows and macOS
- Illustrator 2024 (version 28.7.5 and earlier) on both Windows and macOS
| Risk Factors | Details |
|---|---|
| Affected Products | Adobe Illustrator 2025 (versions ≤29.3), Adobe Illustrator 2024 (versions ≤28.7.5) |
| Impact | Potential for arbitrary code execution |
| Exploit Prerequisites | Requires user interaction; victim must open a malicious .ai or .eps file |
| CVSS 3.1 Score | 7.8 (Critical) |
Mitigation Measures
Adobe has released updates that address this vulnerability in the following versions:
- Illustrator 2025 (version 29.4 and newer)
- Illustrator 2024 (version 28.7.6 and newer)
To ensure protection, users are urged to update their Illustrator software as soon as possible via the Creative Cloud desktop app. Those who have turned off automatic updates will need to manually check for and apply the update.
While Adobe has stated that it has not yet observed any active exploitation of this vulnerability, the situation could change as more information becomes available.
Organizations using Adobe Illustrator should adopt a proactive patch management approach, consider controlling update deployment schedules by disabling automatic updates, and educate users on the dangers of opening files from unfamiliar or unreliable sources.
For those concerned about the potential for exploitation, it is crucial to update the software promptly and remain cautious when handling Illustrator files from unverified or suspicious origins.
