CVE-2025-61802 is a Use After Free (CWE-416) vulnerability identified in Adobe Substance3D - Stager, a 3D design and rendering application widely used in creative industries. The vulnerability exists in versions 3.1.4 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 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 an attacker to execute malicious payloads, escalate privileges, or compromise system integrity. The CVSS v3.1 base score is 7.8, reflecting high severity due to high impact on confidentiality, integrity, and availability, combined with low attack complexity and no required privileges. However, exploitation requires user interaction, specifically opening a malicious file, which somewhat limits the attack vector. No patches or updates have been released at the time of publication, and no active exploits have been reported in the wild. The vulnerability is particularly concerning for organizations relying on Substance3D - Stager for digital content creation, as successful exploitation could lead to significant operational disruption or data compromise.

For European organizations, the impact of CVE-2025-61802 can be substantial, especially in sectors such as digital media, advertising, gaming, and industrial design where Adobe Substance3D - Stager is commonly used. Successful exploitation could lead to unauthorized code execution, resulting in data theft, intellectual property loss, or system compromise. Confidentiality is at risk as attackers could access sensitive design files or proprietary information. Integrity could be undermined by malicious modifications to project files or software behavior. Availability may also be affected if attackers deploy ransomware or disrupt workflows. Given the requirement for user interaction, phishing or social engineering campaigns could be leveraged to deliver malicious files. The lack of a patch increases exposure duration, necessitating immediate risk management. Organizations with remote or hybrid workforces may face elevated risk due to increased file sharing and less controlled environments.

Until Adobe releases a patch, European organizations should implement several targeted mitigations: 1) Enforce strict controls on file sources by restricting the opening of Substance3D - Stager project files to trusted origins only. 2) Deploy advanced endpoint protection solutions capable of detecting and blocking use-after-free exploitation techniques and suspicious file behaviors. 3) Educate users on the risks of opening files from untrusted or unexpected sources, emphasizing phishing awareness. 4) Implement network-level file scanning and sandboxing for files intended for Substance3D - Stager to detect malicious payloads before delivery. 5) Monitor application logs and system behavior for anomalies indicative of exploitation attempts. 6) Consider isolating Substance3D - Stager usage to dedicated virtual machines or containers to limit potential damage. 7) Maintain up-to-date backups of critical design data to enable recovery in case of compromise. 8) Prepare incident response plans specific to this vulnerability to enable rapid containment and remediation once exploitation is detected or a patch is available.
