CVE-2025-54262 is a high-severity out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Stager versions 3.1.3 and earlier. This vulnerability arises when the software parses a specially crafted file, leading to a read operation beyond the allocated memory boundary. Such out-of-bounds reads can cause memory corruption or leakage of sensitive information. More critically, this vulnerability can be leveraged by an attacker to execute arbitrary code within the context of the current user. The attack vector requires user interaction, specifically the opening of a maliciously crafted file by the victim. The CVSS v3.1 base score is 7.8, reflecting a high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. The vulnerability scope is unchanged, meaning the exploit affects only the vulnerable application and not other system components. No known public exploits are reported yet, and no patches have been linked at the time of publication. However, given the potential for code execution, this vulnerability poses a significant risk to users of Adobe Substance3D - Stager, particularly in environments where untrusted files might be received or shared.

For European organizations, the impact of CVE-2025-54262 could be substantial, especially for those in creative industries, digital content creation, and design sectors that rely on Adobe Substance3D - Stager for 3D staging and visualization workflows. Successful exploitation could lead to unauthorized code execution, enabling attackers to compromise user systems, steal intellectual property, or move laterally within corporate networks. This could result in data breaches, disruption of business operations, and potential reputational damage. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files. Given the high confidentiality, integrity, and availability impacts, organizations handling sensitive design assets or proprietary models are at elevated risk. Furthermore, the lack of patches at the time of disclosure increases the urgency for mitigation to prevent exploitation.

European organizations should implement a multi-layered mitigation approach: 1) Restrict the use of Adobe Substance3D - Stager 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 the threat of crafted files. 3) Employ application whitelisting and sandboxing techniques to limit the execution context of Substance3D - Stager, reducing the impact of potential exploitation. 4) Monitor network and endpoint activity for unusual behavior indicative of exploitation attempts, such as unexpected process launches or memory access anomalies. 5) Maintain up-to-date backups of critical design assets to enable recovery in case of compromise. 6) Stay alert for official patches or updates from Adobe and apply them promptly once available. 7) Consider deploying advanced endpoint detection and response (EDR) solutions capable of detecting exploitation patterns related to out-of-bounds memory reads and code execution attempts.
