CVE-2025-64531 is a Use After Free (CWE-416) vulnerability identified in Adobe Substance3D - Stager, a 3D design and visualization software widely used in creative industries. The vulnerability exists in versions 3.1.5 and earlier, where improper memory management leads to a Use After Free condition. This flaw can be triggered when a user opens a maliciously crafted file, causing the program to reference memory that has already been freed. This can result in arbitrary code execution within the context of the current user, potentially allowing an attacker to execute malicious payloads, manipulate data, or disrupt application availability. The CVSS v3.1 score of 7.8 reflects a high severity, with attack vector being local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The vulnerability affects confidentiality, integrity, and availability (all rated high). No patches or exploits are currently publicly available, but the vulnerability is officially published and reserved by Adobe. Given the nature of the software, exploitation would likely target users opening untrusted or unsolicited files, emphasizing the need for cautious file handling.

For European organizations, the impact of CVE-2025-64531 can be significant, particularly for those in industries relying heavily on Adobe Substance3D - Stager, such as digital media, animation, gaming, and product design. Successful exploitation could lead to unauthorized code execution, data theft, or sabotage of design projects, potentially causing intellectual property loss and operational disruption. Since the vulnerability executes code with the current user's privileges, the extent of damage depends on user rights; users with elevated privileges could face more severe consequences. The requirement for user interaction limits mass exploitation but does not eliminate targeted attacks, especially via phishing or social engineering. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future attacks. European organizations with remote or hybrid work models may face increased exposure if users handle files from untrusted sources outside secure networks.

1. Monitor Adobe's official channels closely for security patches addressing CVE-2025-64531 and apply updates promptly once available. 2. Until patches are released, implement strict file validation and sandboxing policies for files opened in Substance3D - Stager, especially those received from external or untrusted sources. 3. Educate users on the risks of opening unsolicited or suspicious files and enforce security awareness training focused on social engineering and phishing tactics. 4. Employ endpoint protection solutions capable of detecting anomalous behavior or exploitation attempts related to Use After Free vulnerabilities. 5. Restrict Substance3D - Stager usage to users with minimal necessary privileges to limit potential damage from exploitation. 6. Utilize application whitelisting and network segmentation to reduce the attack surface and contain potential breaches. 7. Implement monitoring and logging to detect unusual application crashes or execution patterns that may indicate exploitation attempts.
