CVE-2025-61834 is a Use After Free vulnerability (CWE-416) found in Adobe Substance3D - Stager, a 3D design and visualization application widely used in creative industries. The flaw exists in versions 3.1.5 and earlier, where improper handling of memory leads to a Use After Free condition. This vulnerability can be triggered when a user opens a maliciously crafted file, causing the application to reference memory that has already been freed. This can result in arbitrary code execution within the context of the current user, potentially allowing attackers to execute malicious payloads, escalate privileges, or compromise system integrity. The CVSS v3.1 base score is 7.8, reflecting high severity with attack vector local (requiring user interaction), low attack complexity, no privileges required, and user interaction necessary. The impact affects confidentiality, integrity, and availability. No patches or mitigations have been officially released yet, and no known exploits are currently active in the wild. The vulnerability highlights the risk posed by opening untrusted files in creative software environments.

For European organizations, especially those in the digital content creation, media, and design sectors, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, data theft, or system compromise, impacting sensitive intellectual property and business continuity. Since the attack requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The compromise of workstations could serve as a foothold for lateral movement within corporate networks, potentially affecting broader IT infrastructure. The confidentiality of proprietary designs and client data could be jeopardized, and operational disruptions could occur if systems are destabilized or malware is deployed. Organizations relying heavily on Adobe Substance3D - Stager for their workflows are particularly vulnerable until patches are available.

Until Adobe releases an official patch, European organizations should implement specific mitigations: 1) Enforce strict controls on file sources by restricting the opening of files from untrusted or unknown origins within Substance3D - Stager. 2) Educate users on the risks of opening unsolicited or suspicious files, emphasizing caution with email attachments and downloads. 3) Deploy endpoint detection and response (EDR) solutions to monitor for anomalous behaviors indicative of exploitation attempts. 4) Use application whitelisting and sandboxing techniques to limit the execution scope of Substance3D - Stager processes. 5) Regularly back up critical project files and maintain offline copies to reduce impact from potential compromise. 6) Monitor Adobe’s security advisories closely for patch releases and apply updates promptly. 7) Consider network segmentation to isolate systems running Substance3D - Stager from sensitive infrastructure.
