CVE-2025-54194 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 input data, leading to the potential disclosure of sensitive memory contents. The flaw requires user interaction, specifically that a victim must open a maliciously crafted file to trigger the vulnerability. Upon successful exploitation, an attacker could read memory beyond the intended buffer limits, potentially exposing sensitive information such as cryptographic keys, user credentials, or other confidential data stored in memory. The vulnerability does not allow modification of data or denial of service but compromises confidentiality. The CVSS 3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), requires no privileges (PR:N), but does require user interaction (UI:R). The attack complexity is low (AC:L), and the impact is limited to confidentiality (C:H), with no impact on integrity or availability. No known exploits are currently in the wild, and no patches have been linked yet. This vulnerability is significant for users of Adobe Substance3D - Painter, a professional 3D painting and texturing tool widely used in digital content creation, gaming, and visual effects industries.

For European organizations, the impact of this vulnerability depends largely on their use of Adobe Substance3D - Painter within their workflows. Companies involved in digital media, game development, advertising, and visual effects production are at higher risk, as they are more likely to use this software. The exposure of sensitive memory could lead to leakage of intellectual property, proprietary textures, or other confidential project data, potentially resulting in competitive disadvantage or reputational damage. Although the vulnerability does not allow code execution or system compromise, the confidentiality breach could facilitate further targeted attacks if sensitive credentials or cryptographic material are exposed. The requirement for user interaction (opening a malicious file) means that social engineering or phishing campaigns could be used to deliver the exploit. Given the creative industry's importance in Europe, especially in countries with strong digital media sectors, this vulnerability could have a notable impact if exploited.

To mitigate this vulnerability, European organizations should: 1) Immediately audit and inventory all instances of Adobe Substance3D - Painter in use, identifying versions 11.0.2 and earlier. 2) Restrict the opening of files from untrusted or unknown sources within the software environment, implementing strict file validation policies. 3) Educate users on the risks of opening files from unverified origins and train them to recognize phishing or social engineering attempts that could deliver malicious files. 4) Implement network-level controls to block or monitor file transfers that could carry malicious Substance3D project files. 5) Monitor Adobe's official channels for patches or updates addressing CVE-2025-54194 and apply them promptly once available. 6) Consider sandboxing or running Substance3D - Painter in isolated environments to limit potential data exposure. 7) Employ endpoint detection and response (EDR) tools to detect anomalous behaviors related to file handling within the application. These measures go beyond generic advice by focusing on controlling file provenance, user awareness, and environment isolation specific to this vulnerability's exploitation vector.
