CVE-2025-54262 is a high-severity vulnerability affecting Adobe Substance3D - Stager versions 3.1.3 and earlier. The issue is an out-of-bounds read (CWE-125) that occurs when the software parses a specially crafted file. This vulnerability allows an attacker to read memory beyond the allocated buffer, potentially leading to arbitrary code execution within the context of the current user. The exploitation requires user interaction, specifically the victim opening a maliciously crafted file. The CVSS 3.1 base score is 7.8, reflecting a high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. The vulnerability arises from improper bounds checking during file parsing, which can be leveraged to execute arbitrary code, potentially compromising the affected system. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize monitoring and mitigation efforts. Adobe Substance3D - Stager is a 3D design and staging application used primarily by creative professionals for visual content creation, which means the threat primarily targets users in creative industries and organizations relying on this software for design workflows.

For European organizations, this vulnerability poses a significant risk, especially for companies in the creative, media, advertising, and design sectors that utilize Adobe Substance3D - Stager. Successful exploitation could lead to unauthorized code execution, resulting in data theft, intellectual property compromise, or disruption of design workflows. Given the high confidentiality and integrity impact, sensitive design assets and proprietary information could be exposed or altered. The requirement for user interaction (opening a malicious file) suggests that targeted phishing or social engineering campaigns could be used to deliver the exploit. This risk extends to organizations with remote or hybrid work environments where file sharing is common. Additionally, compromised endpoints could serve as footholds for lateral movement within corporate networks, potentially affecting broader IT infrastructure. The absence of known exploits in the wild provides a window for proactive defense, but the high CVSS score indicates that once exploited, the consequences could be severe.

European organizations should implement a multi-layered defense approach tailored to this vulnerability: 1) Immediately inventory and identify all installations of Adobe Substance3D - Stager to understand exposure. 2) Restrict or monitor the opening of files from untrusted or unknown sources, especially those received via email or external file-sharing platforms. 3) Educate users, particularly creative teams, about the risks of opening unsolicited or suspicious files and promote awareness of social engineering tactics. 4) Employ endpoint detection and response (EDR) solutions capable of detecting anomalous process behavior indicative of exploitation attempts. 5) Use application whitelisting and sandboxing where possible to limit the execution context of Adobe Substance3D - Stager. 6) Monitor for updates or patches from Adobe and prioritize rapid deployment once available. 7) Implement network segmentation to limit potential lateral movement if a system is compromised. 8) Regularly back up critical design assets and verify the integrity of backups to enable recovery from potential compromise. These measures go beyond generic advice by focusing on the specific attack vector (malicious file parsing) and the user base likely to be targeted.
