CVE-2025-49530 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe Illustrator versions 28.7.6, 29.5.1, and earlier. This vulnerability arises from improper handling of memory bounds within the application, allowing an attacker to write data outside the intended buffer limits. Such memory corruption can lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically the opening of a maliciously crafted Illustrator file. The vulnerability has a CVSS 3.1 base score of 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. The scope remains unchanged, meaning the impact is confined to the vulnerable application and user context. Although no known exploits are currently reported in the wild, the nature of the vulnerability makes it a significant risk, especially in environments where Illustrator files are frequently exchanged or downloaded from untrusted sources. The lack of available patches at the time of publication increases the urgency for organizations to implement interim mitigations. Given Illustrator's widespread use in creative industries, this vulnerability could be leveraged to execute malicious code, potentially leading to data theft, system compromise, or lateral movement within networks.

For European organizations, the impact of this vulnerability is considerable, particularly for those in sectors heavily reliant on Adobe Illustrator, such as advertising, media, design, and publishing. Successful exploitation could lead to unauthorized access to sensitive intellectual property, disruption of creative workflows, and potential compromise of corporate networks if the attacker escalates privileges or moves laterally. The requirement for user interaction means that social engineering or phishing campaigns could be used to deliver malicious files, increasing the risk in organizations with less stringent email and file handling policies. Additionally, compromised systems could be used as footholds for broader attacks, affecting confidentiality and availability of critical business data. The vulnerability's ability to execute arbitrary code also raises concerns about ransomware deployment or espionage activities targeting European creative industries and government entities using Illustrator.

Given the absence of patches at the time of disclosure, European organizations should implement the following specific mitigations: 1) Enforce strict email and file attachment filtering to block or quarantine Illustrator files from untrusted or unknown sources. 2) Educate users, especially creative teams, about the risks of opening unsolicited or unexpected Illustrator files and encourage verification of file origins. 3) Employ application whitelisting and sandboxing techniques to limit the execution context of Illustrator, reducing the impact of potential exploitation. 4) Monitor network and endpoint behavior for anomalies indicative of exploitation attempts, such as unusual process spawning or memory access patterns. 5) Maintain up-to-date backups of critical creative assets to enable recovery in case of compromise. 6) Once Adobe releases patches, prioritize immediate deployment across all affected systems. 7) Consider disabling or restricting Illustrator usage on systems where it is not essential to minimize the attack surface.
