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 bounds while processing certain data structures, leading to the potential disclosure of sensitive memory contents. Specifically, when a user opens a specially crafted malicious file, the application may read memory beyond the intended buffer limits. This can expose sensitive information residing in adjacent memory areas, such as user data, cryptographic keys, or other confidential information held in process memory. The vulnerability requires user interaction, meaning an attacker must convince a victim to open a malicious file, which triggers the out-of-bounds read. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), requires low attack complexity (AC:L), no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to confidentiality (C:H), with no impact on integrity or availability. No known exploits are reported in the wild as of the publication date (August 12, 2025), and no patches or mitigations have been officially released yet. The vulnerability is specific to Adobe Substance3D - Modeler, a 3D modeling software used primarily in creative industries for digital content creation.

For European organizations, the primary impact of CVE-2025-54204 is the potential leakage of sensitive information through memory disclosure when users open malicious files in Adobe Substance3D - Modeler. Organizations in sectors such as media, entertainment, design, and digital content creation that rely on this software could face confidentiality breaches, potentially exposing intellectual property, proprietary designs, or personal data. While the vulnerability does not affect system integrity or availability, the exposure of sensitive memory contents could facilitate further attacks or data leaks. Given that exploitation requires user interaction, targeted phishing or social engineering campaigns could be used to deliver malicious files. The medium severity rating suggests a moderate risk; however, the impact could be significant for organizations handling sensitive or regulated data. Additionally, the lack of known exploits currently reduces immediate risk but does not eliminate the threat as attackers may develop exploits over time. European organizations must be vigilant, especially those with creative teams using Adobe Substance3D - Modeler, to prevent potential data leakage and comply with data protection regulations such as GDPR.

To mitigate the risk posed by 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 on the risks of opening files from unknown or untrusted sources, emphasizing caution with email attachments and downloads. 3) Implement application whitelisting and sandboxing for Adobe Substance3D - Modeler to contain potential exploitation attempts and prevent unauthorized data access. 4) Monitor and control file sharing channels to detect and block malicious files targeting this vulnerability. 5) Maintain up-to-date backups and incident response plans tailored to potential data leakage incidents. 6) Engage with Adobe for timely updates and patches; once available, prioritize deployment of security updates for Substance3D - Modeler. 7) Use endpoint detection and response (EDR) tools to identify anomalous behaviors related to file opening or memory access within the application. 8) Consider network segmentation to isolate systems running Substance3D - Modeler from critical infrastructure to limit lateral movement in case of exploitation.
