CVE-2025-54193 is an out-of-bounds read vulnerability (CWE-125) identified in Adobe Substance3D - Painter versions 11.0.2 and earlier. This vulnerability arises when the software improperly handles memory boundaries while processing certain inputs, leading to the potential disclosure of sensitive memory contents. Specifically, an attacker can craft a malicious file that, when opened by a user in the affected application, triggers the out-of-bounds read condition. This results in unauthorized reading of memory areas beyond the intended buffer limits, potentially exposing sensitive data such as cryptographic keys, user credentials, or other confidential information stored in memory. The vulnerability requires user interaction, meaning the victim must actively open a maliciously crafted file for exploitation to occur. The CVSS v3.1 base score is 5.5, indicating a medium severity level. The vector details (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) show that the attack requires local access (local vector), low attack complexity, no privileges, user interaction, unchanged scope, high confidentiality impact, no integrity or availability impact. Currently, there are no known exploits in the wild, and no patches have been linked yet, suggesting that remediation may still be pending or in development. This vulnerability is significant because Adobe Substance3D - Painter is widely used in digital content creation, including by professionals in gaming, film, and design industries, where sensitive intellectual property and proprietary assets may be at risk if memory disclosure occurs.

For European organizations, the impact of CVE-2025-54193 could be substantial, particularly for companies involved in digital media, animation, gaming, and design sectors that rely on Adobe Substance3D - Painter for content creation. The disclosure of sensitive memory could lead to leakage of proprietary design data, trade secrets, or user credentials, potentially enabling further attacks such as targeted phishing or intellectual property theft. Although the vulnerability does not allow code execution or system compromise directly, the confidentiality breach can undermine competitive advantage and client trust. Additionally, organizations subject to strict data protection regulations such as GDPR may face compliance risks if sensitive personal or corporate data is exposed. The requirement for user interaction somewhat limits the attack surface, but social engineering tactics could be employed to trick users into opening malicious files, especially in collaborative environments where file sharing is common. The absence of known exploits in the wild currently reduces immediate risk, but the medium severity and potential for sensitive data exposure warrant proactive measures.

To mitigate the risk posed by CVE-2025-54193, European organizations should implement a multi-layered approach: 1) Restrict the use of Adobe Substance3D - Painter to trusted users and environments, limiting exposure to untrusted files. 2) Educate users on the risks of opening files from unknown or unverified sources, emphasizing caution with files received via email or external collaborators. 3) Monitor for updates and patches from Adobe and apply them promptly once available to remediate the vulnerability. 4) Employ application whitelisting and sandboxing techniques to isolate the Substance3D - Painter application, reducing the impact of potential exploitation. 5) Implement network segmentation to limit access to sensitive design assets and reduce lateral movement opportunities. 6) Use endpoint detection and response (EDR) tools to identify anomalous behaviors related to file handling and memory access within the application. 7) Maintain regular backups of critical design data to ensure recovery in case of data compromise. These targeted actions go beyond generic advice by focusing on user behavior, application control, and proactive patch management specific to the affected software and vulnerability characteristics.
