CVE-2025-61803 identifies an integer overflow or wraparound vulnerability (CWE-190) in Adobe Substance3D - Stager, a 3D design and rendering application widely used in creative industries. The flaw exists in versions 3.1.4 and earlier, where improper handling of integer values during file processing can lead to overflow conditions. This can corrupt memory or cause unexpected behavior, ultimately allowing an attacker to execute arbitrary code within the context of the current user. Exploitation requires the victim to open a maliciously crafted file, making user interaction mandatory. The vulnerability does not require prior authentication, increasing its risk profile. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction. No patches or exploits are currently publicly available, but the vulnerability is published and should be considered a significant risk. The flaw could be leveraged to compromise systems, steal sensitive data, or disrupt operations, especially in environments where Substance3D - Stager is used for critical design workflows.

For European organizations, the impact of CVE-2025-61803 can be substantial, particularly in sectors relying heavily on Adobe Substance3D - Stager such as media production, advertising, gaming, and industrial design. Successful exploitation could lead to unauthorized code execution, resulting in data breaches, intellectual property theft, or disruption of design processes. Since the vulnerability allows code execution with user-level privileges, attackers could pivot to escalate privileges or move laterally within networks. The requirement for user interaction means phishing or social engineering campaigns could be effective attack vectors. The compromise of design assets or proprietary models could have financial and reputational consequences. Additionally, availability impacts could delay project timelines. Given the widespread use of Adobe products in Europe, the threat is relevant across multiple industries and organizational sizes.

1. Immediately monitor Adobe’s official channels for patches or updates addressing this vulnerability and apply them promptly once available. 2. Until patches are released, implement strict controls on file sources by restricting the opening of Substance3D - Stager files from untrusted or unknown origins. 3. Educate users on the risks of opening unsolicited or suspicious files, emphasizing the importance of verifying file authenticity. 4. Employ endpoint protection solutions capable of detecting anomalous behavior or exploitation attempts related to Adobe applications. 5. Use application whitelisting to limit execution of unauthorized code within the Substance3D environment. 6. Implement network segmentation to contain potential breaches originating from compromised user machines. 7. Regularly back up critical design files and maintain incident response plans tailored to creative and design environments. 8. Monitor logs and alerts for unusual activity involving Substance3D - Stager processes or file accesses. These targeted measures go beyond generic advice by focusing on the specific attack vector and user interaction requirement.
