CVE-2025-54195 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 bounds while processing certain data structures, leading to the potential disclosure of sensitive memory contents. The flaw can be triggered when a user opens a specially crafted malicious file within the application. Because the vulnerability involves an out-of-bounds read, it does not allow direct code execution or modification of data but can expose sensitive information residing in adjacent memory areas. 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 scope is unchanged (S:U), and the impact is high on confidentiality (C:H) but none on integrity or availability (I:N, A:N). No known exploits are currently reported in the wild, and no patches or updates have been linked yet. This vulnerability is significant for users who frequently open files from untrusted sources in Substance3D - Painter, as it could lead to leakage of sensitive information such as project data, credentials, or other in-memory secrets.

For European organizations, especially those in creative industries, digital media, gaming, and design sectors that rely on Adobe Substance3D - Painter, this vulnerability poses a risk of sensitive data leakage. Confidential project files, proprietary assets, or user credentials stored or processed in memory could be exposed if a malicious file is opened. While the vulnerability does not allow code execution or system compromise, the confidentiality breach could lead to intellectual property theft or leakage of sensitive business information. The requirement for user interaction limits mass exploitation but targeted spear-phishing or social engineering campaigns could be effective. Organizations with remote or hybrid work environments may face increased risk if users open untrusted files received via email or collaboration platforms. The absence of a patch increases the urgency for temporary mitigations. The impact on operational continuity is low, but the potential for data confidentiality loss is significant, especially for organizations handling sensitive creative content or client data.

1. Implement strict file handling policies: Educate users to avoid opening files from untrusted or unknown sources in Substance3D - Painter. 2. Use sandboxing or isolated environments when opening files from external sources to limit memory exposure. 3. Monitor and restrict the use of Substance3D - Painter to trusted personnel and ensure that files are scanned with updated antivirus and endpoint detection tools before opening. 4. Employ network segmentation to limit exposure of systems running Substance3D - Painter to external threats. 5. Maintain up-to-date backups of critical project files to mitigate risks from potential exploitation. 6. Monitor Adobe’s security advisories closely for patches or updates addressing this vulnerability and apply them promptly upon release. 7. Consider application whitelisting and endpoint protection solutions that can detect anomalous behavior related to file processing. 8. Implement Data Loss Prevention (DLP) controls to detect and prevent unauthorized exfiltration of sensitive data that might be exposed through this vulnerability.
