CVE-2025-54192 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Painter versions 11.0.2 and earlier. This vulnerability arises when the software improperly handles memory boundaries while processing certain inputs, specifically when opening crafted malicious files. An out-of-bounds read occurs when the program reads data outside the allocated memory buffer, potentially exposing sensitive information stored in adjacent memory regions. Exploitation requires user interaction, as the victim must open a malicious file designed to trigger this flaw. The vulnerability does not allow modification of data or denial of service but can lead to disclosure of sensitive memory contents, which may include confidential project data or other sensitive information residing in the application's memory space. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the local attack vector (AV:L), low complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). There are no known exploits in the wild at the time of publication, and no patches have been released yet. The vulnerability is specific to Adobe Substance3D - Painter, a widely used 3D texturing and material authoring tool in creative industries.

For European organizations, especially those in creative sectors such as gaming, film production, advertising, and industrial design, this vulnerability poses a risk of sensitive intellectual property leakage. Since the vulnerability can disclose memory contents, attackers could potentially extract proprietary textures, designs, or other confidential data embedded in the application’s memory. This could lead to loss of competitive advantage or exposure of client data. The requirement for user interaction (opening a malicious file) limits remote exploitation but does not eliminate risk, particularly in environments where files are shared frequently or received from external collaborators. The medium severity score indicates a moderate risk level; however, the confidentiality impact is high, which is critical for organizations handling sensitive creative assets. The absence of known exploits reduces immediate threat but vigilance is necessary as attackers may develop exploits once the vulnerability details are public. Additionally, the lack of a patch means organizations must rely on mitigation strategies until Adobe releases an update.

European organizations should implement strict file handling policies, including verifying the source and integrity of files before opening them in Substance3D - Painter. Employ sandboxing or isolated environments for opening files from untrusted sources to contain potential memory disclosure. Educate users about the risks of opening files from unknown or untrusted origins, emphasizing the necessity of user caution. Monitor network and endpoint activity for unusual file transfers or suspicious behavior related to Substance3D usage. Utilize endpoint detection and response (EDR) tools to detect anomalous memory access patterns or attempts to exploit memory vulnerabilities. Maintain up-to-date backups of critical project files to mitigate indirect impacts. Engage with Adobe’s security advisories to promptly apply patches once available. Consider restricting Substance3D - Painter usage to trusted personnel and environments until the vulnerability is resolved.
