CVE-2025-49564 is a stack-based buffer overflow vulnerability identified in Adobe Illustrator versions 28.7.8, 29.6.1, and earlier. The vulnerability arises from improper handling of data within the application, allowing an attacker to overwrite the stack memory. This can lead to arbitrary code execution in the context of the current user, potentially compromising system confidentiality, integrity, and availability. Exploitation requires a victim to open a specially crafted malicious Illustrator file, making user interaction mandatory. The vulnerability is classified under CWE-121, indicating a classic stack-based buffer overflow issue. The CVSS v3.1 base score is 7.8, reflecting high severity with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The flaw could be leveraged by attackers to execute arbitrary code, potentially leading to full system compromise depending on user privileges. Given Adobe Illustrator's widespread use in creative industries, this vulnerability poses a significant risk to organizations relying on this software for design and production workflows.

The impact of CVE-2025-49564 is substantial for organizations using affected Adobe Illustrator versions. Successful exploitation can lead to arbitrary code execution, enabling attackers to install malware, steal sensitive data, or disrupt operations. Since the code executes with the current user's privileges, the extent of damage depends on the user's access rights; administrative users face greater risk. The vulnerability affects confidentiality by exposing sensitive design files and intellectual property, integrity by allowing unauthorized modification of files or system settings, and availability by potentially crashing the application or system. Industries relying heavily on Adobe Illustrator, such as graphic design, advertising, publishing, and media production, could experience operational disruptions and data breaches. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where users frequently receive external files. The absence of known exploits in the wild currently reduces immediate threat but does not preclude future active exploitation. Organizations worldwide with significant Adobe Illustrator deployments are vulnerable until patches or mitigations are applied.

1. Monitor Adobe's official channels for security updates and apply patches immediately once released to address CVE-2025-49564. 2. Until patches are available, restrict the opening of Illustrator files from untrusted or unknown sources through email filtering, endpoint protection, and user training. 3. Implement application whitelisting and sandboxing to limit the execution context of Adobe Illustrator and contain potential exploits. 4. Educate users about the risks of opening unsolicited or suspicious files, emphasizing verification of file sources. 5. Employ network segmentation to isolate systems running Illustrator, reducing lateral movement if compromise occurs. 6. Use endpoint detection and response (EDR) tools to monitor for anomalous behavior indicative of exploitation attempts. 7. Regularly back up critical design files and maintain version control to recover from potential data corruption or loss. 8. Review and enforce least privilege principles for user accounts to minimize the impact of code execution under user context. 9. Consider disabling or limiting macros or scripting features within Illustrator if applicable, to reduce attack surface. 10. Conduct periodic security awareness training focused on social engineering and file-based attack vectors.
