CVE-2025-61806 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Substance3D - Stager versions 3.1.4 and earlier. The vulnerability arises during the parsing of specially crafted files, where the application reads beyond the allocated memory buffer boundaries. This memory corruption can be leveraged by an attacker to execute arbitrary code within the context of the current user, potentially compromising system confidentiality, integrity, and availability. The attack vector requires local access to the victim and user interaction, as the victim must open a malicious file crafted to exploit this flaw. The CVSS v3.1 base score is 7.8, reflecting high severity due to the potential for remote code execution with low attack complexity and no privileges required, but user interaction is necessary. Although no public exploits have been reported, the vulnerability poses a significant risk to users of Adobe Substance3D - Stager, a tool widely used in 3D content creation and design workflows. The lack of available patches at the time of publication necessitates immediate mitigation efforts. The vulnerability's exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, system compromise, or disruption of creative workflows.

For European organizations, particularly those in digital media, design, and creative industries that utilize Adobe Substance3D - Stager, this vulnerability presents a significant risk. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal sensitive intellectual property, disrupt operations, or establish persistence within networks. The confidentiality of proprietary 3D models and design files could be compromised, impacting competitive advantage and client trust. Integrity of design assets may be altered, causing downstream effects in production pipelines. Availability could also be affected if attackers deploy destructive payloads or ransomware. Given the user interaction requirement, phishing or social engineering campaigns could be used to deliver malicious files, increasing the threat surface. The lack of known exploits currently reduces immediate risk but does not eliminate the potential for targeted attacks, especially against high-value creative organizations in Europe.

1. Immediately restrict the opening of files from untrusted or unknown sources within Adobe Substance3D - Stager environments. 2. Implement strict email filtering and user training to reduce the risk of phishing attacks delivering malicious files. 3. Employ application whitelisting to prevent execution of unauthorized files or scripts. 4. Monitor file system and process behaviors for anomalies related to Substance3D - Stager usage, including unexpected file access or crashes. 5. Isolate workstations used for 3D content creation from critical network segments to limit lateral movement if compromise occurs. 6. Regularly back up critical design assets and maintain offline copies to ensure recovery in case of compromise. 7. Stay alert for Adobe security advisories and apply patches promptly once available. 8. Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation attempts targeting memory corruption vulnerabilities. 9. Enforce the principle of least privilege for users running Substance3D - Stager to limit the impact of potential code execution.
