CVE-2025-54200 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 data structures, leading to the possibility of reading memory outside the intended buffer. Exploitation requires user interaction, specifically the opening of a maliciously crafted file by the victim. Successful exploitation can result in disclosure of sensitive memory contents, potentially exposing confidential information such as cryptographic keys, passwords, or other sensitive data residing in adjacent memory regions. The vulnerability does not allow modification of data or denial of service but compromises confidentiality. The CVSS v3.1 base score is 5.5 (medium severity), with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high impact on confidentiality (C:H), and no impact on integrity or availability (I:N/A:N). No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation may require vendor updates or workarounds once available.

For European organizations, the primary impact of this vulnerability is the potential leakage of sensitive information through memory disclosure. Organizations using Adobe Substance3D - Modeler, particularly in industries such as digital content creation, design, gaming, and media production, may face risks of intellectual property exposure or leakage of confidential project data. Since exploitation requires user interaction (opening a malicious file), the threat vector is likely through targeted spear-phishing or supply chain attacks distributing crafted model files. Confidentiality breaches could lead to competitive disadvantages, regulatory compliance issues (e.g., GDPR concerns if personal data is exposed), and reputational damage. However, the lack of impact on integrity and availability limits the risk of operational disruption. The medium severity score reflects these factors, but organizations should remain vigilant due to the sensitive nature of the data potentially exposed.

1. Immediate mitigation involves user awareness training to avoid opening untrusted or unsolicited Substance3D model files, especially from unknown sources. 2. Implement strict file validation and sandboxing policies for handling 3D model files within the organization to contain potential exploitation. 3. Monitor Adobe's security advisories closely for patches or updates addressing this vulnerability and apply them promptly upon release. 4. Employ endpoint protection solutions capable of detecting anomalous behavior related to file processing in Substance3D - Modeler. 5. Restrict Substance3D - Modeler usage to trusted users and environments, and consider network segmentation to limit exposure. 6. Conduct regular security assessments and penetration testing focusing on file handling applications to identify similar vulnerabilities proactively.
