CVE-2025-30313 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Illustrator versions 28.7.6, 29.5.1, and earlier. This vulnerability arises when Illustrator processes specially crafted malicious files, leading to the application reading memory outside the intended buffer boundaries. Such out-of-bounds reads can result in the disclosure of sensitive memory contents, potentially exposing confidential information held in the application's memory space. Exploitation requires user interaction, specifically the victim opening a malicious Illustrator file. The vulnerability does not allow for code execution or modification of data, but the confidentiality impact is high due to possible leakage of sensitive information. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity (I:N) or availability (A:N). There are no known exploits in the wild at this time, and no patches or updates have been linked yet. This vulnerability highlights the risk of handling untrusted Illustrator files and the importance of cautious file handling and timely patching once fixes become available.

For European organizations, the primary impact of CVE-2025-30313 lies in the potential exposure of sensitive information through memory disclosure. Organizations using Adobe Illustrator for design, marketing, publishing, or creative content production may inadvertently expose confidential data if employees open malicious files. This could include intellectual property, client data, or internal project details. While the vulnerability does not enable system compromise or persistent control, the confidentiality breach could facilitate further targeted attacks or corporate espionage. Sectors such as media, advertising, manufacturing, and any industry relying heavily on graphic design tools are at risk. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted spear-phishing or social engineering attacks leveraging malicious Illustrator files. The absence of known exploits suggests a window for proactive mitigation. However, the medium severity and high confidentiality impact warrant immediate attention to prevent data leakage incidents.

European organizations should implement the following specific mitigations: 1) Enforce strict email and file attachment filtering policies to detect and quarantine suspicious Illustrator files, especially from unknown or untrusted sources. 2) Educate users about the risks of opening unsolicited or unexpected Illustrator files and train them to verify file origins before opening. 3) Employ endpoint protection solutions capable of sandboxing or analyzing Illustrator files for anomalous behavior prior to allowing execution. 4) Maintain an inventory of Adobe Illustrator versions in use and prioritize upgrading to patched versions as soon as Adobe releases fixes for this vulnerability. 5) Implement application whitelisting or controlled use policies limiting Illustrator usage to trusted users and environments. 6) Monitor network and host logs for unusual file access or memory disclosure indicators related to Illustrator processes. 7) Coordinate with Adobe support channels to receive timely updates and advisories. These measures go beyond generic advice by focusing on user behavior, file filtering, and proactive monitoring tailored to the nature of this vulnerability.
