CVE-2025-54204 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Modeler versions 1.22.0 and earlier. This vulnerability arises when the software improperly handles memory boundaries while processing certain inputs, leading to the potential disclosure of sensitive memory contents. Specifically, an attacker can craft a malicious file that, when opened by a user in the vulnerable application, triggers the out-of-bounds read condition. This can result in unauthorized exposure of sensitive data residing in adjacent memory areas, which may include confidential information or cryptographic material. The vulnerability requires user interaction, as the victim must open the malicious file for exploitation to occur. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), with low attack complexity (AC:L), no privileges required (PR:N), but user interaction is necessary (UI:R). The impact is limited to confidentiality (C:H), with no impact on integrity or availability. There are no known exploits in the wild at the time of publication, and no patches have been released yet. This vulnerability is significant for users of Adobe Substance3D - Modeler, a 3D modeling tool used in creative industries for digital content creation, including gaming, animation, and design workflows.

For European organizations, the impact of CVE-2025-54204 depends on the extent to which Adobe Substance3D - Modeler is used within their digital content creation pipelines. Organizations in sectors such as media, entertainment, advertising, and design that rely on this software could face confidentiality risks if attackers exploit this vulnerability to extract sensitive project data or intellectual property. Although the vulnerability does not affect integrity or availability, the exposure of sensitive memory could lead to leakage of proprietary assets or user credentials stored in memory, potentially facilitating further attacks. The requirement for user interaction reduces the risk of widespread automated exploitation but does not eliminate targeted spear-phishing or social engineering attacks aimed at creative professionals. Given the medium severity and lack of known exploits, the immediate risk is moderate; however, the potential for sensitive data disclosure warrants proactive mitigation, especially in organizations handling valuable digital assets or subject to strict data protection regulations such as GDPR.

To mitigate CVE-2025-54204, European organizations should implement the following specific measures: 1) Restrict the use of Adobe Substance3D - Modeler to trusted users and environments, minimizing exposure to untrusted files. 2) Educate users, particularly creative teams, about the risks of opening files from unknown or unverified sources to reduce the likelihood of successful social engineering attacks. 3) Employ application whitelisting and sandboxing techniques to isolate the Substance3D - Modeler process, limiting the impact of potential memory disclosures. 4) Monitor network and endpoint activity for unusual file openings or suspicious behavior related to the application. 5) Maintain up-to-date backups of critical project files to ensure recovery in case of compromise. 6) Engage with Adobe’s security advisories and promptly apply patches or updates once available. 7) Consider implementing Data Loss Prevention (DLP) solutions to detect and prevent unauthorized exfiltration of sensitive data that might result from exploitation. These targeted steps go beyond generic advice by focusing on user behavior, process isolation, and proactive monitoring tailored to the creative software environment.
