CVE-2025-49573 is a high-severity vulnerability identified in Adobe Substance3D - Modeler versions 1.22.0 and earlier. The vulnerability is classified as an out-of-bounds write (CWE-787), which occurs when the software writes data outside the boundaries of allocated memory buffers. This flaw can lead to arbitrary code execution within the security context of the current user. The exploitation vector requires user interaction, specifically the opening of a maliciously crafted file by the victim. Upon successful exploitation, an attacker could execute arbitrary code, potentially leading to full compromise of the affected user's environment, including unauthorized access, data manipulation, or disruption of services. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required but user interaction necessary. No known exploits are currently reported in the wild, and no patches have been published at the time of this analysis. The vulnerability affects a specialized 3D modeling application widely used in creative industries for content creation, design, and visualization workflows.

For European organizations, especially those in sectors such as digital media, gaming, architecture, and industrial design that rely on Adobe Substance3D - Modeler, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized code execution, enabling attackers to steal intellectual property, manipulate design files, or establish persistence within corporate networks. Given the high confidentiality and integrity impact, sensitive design data could be exposed or altered, potentially causing financial loss, reputational damage, and disruption of critical creative workflows. The requirement for user interaction means targeted phishing or social engineering campaigns could be used to deliver malicious files. Organizations with remote or hybrid workforces may face increased risk if users open untrusted files outside secure environments. Additionally, the lack of a patch at present increases the window of exposure until Adobe releases an update.

European organizations should implement a multi-layered defense strategy: 1) Educate users on the risks of opening files from untrusted sources, emphasizing caution with email attachments and downloads. 2) Employ advanced email filtering and endpoint protection solutions capable of detecting and blocking malicious files targeting this vulnerability. 3) Restrict the use of Adobe Substance3D - Modeler to trusted users and environments, and consider application whitelisting to prevent unauthorized execution of malicious payloads. 4) Monitor network and endpoint logs for unusual behavior indicative of exploitation attempts. 5) Isolate systems running Substance3D - Modeler from critical infrastructure to limit lateral movement. 6) Maintain regular backups of design files to enable recovery in case of compromise. 7) Stay alert for Adobe’s security advisories and apply patches promptly once available. 8) Consider deploying sandboxing technologies to safely open untrusted files in controlled environments.
