Adobe Substance3D Modeler versions 1.22.4 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. This vulnerability has been classified with a CVSS score of 7.8, indicating a high severity level. Organizations using affected versions should understand the potential risks and take steps to mitigate them.
Risk to organizations includes unauthorized execution of arbitrary code that can lead to data breaches or system compromise. Given the nature of this vulnerability and its requirement for user interaction, it highlights the importance of user awareness and training. Organizations should prioritize patching immediately.
As of now, there are no known exploits in the wild, but the potential for exploitation remains a concern. Users and administrators should remain vigilant and ensure that proper security measures are in place to prevent unauthorized access.
With the increasing number of vulnerabilities reported, organizations must implement a robust vulnerability management program. Regular updates and patches are crucial in maintaining the security posture of systems.
Vulnerability Details
This vulnerability allows arbitrary code execution through an out-of-bounds write. The affected component is Adobe Substance3D Modeler, specifically versions 1.22.4 and earlier. The CVSS score of 7.8 indicates a high severity, with impacts on confidentiality, integrity, and availability rated as high. The publication date for this vulnerability is January 13, 2026.
Technical Analysis
The root cause of this vulnerability is an out-of-bounds write operation, which can be exploited when a user opens a specially crafted file. The attack vector is local, requiring the attacker to convince the user to open the malicious file. The attack complexity is low, and no privileges are required to exploit this vulnerability.
User interaction is required for exploitation, increasing the likelihood of successful attacks if users are not adequately trained. The high impact on confidentiality, integrity, and availability underscores the severity of this vulnerability.
Risk & Impact Analysis
The potential risk to organizations includes arbitrary code execution, which can lead to unauthorized access, data exfiltration, or complete system compromise. In environments where Adobe Substance3D is used extensively, the blast radius of such an exploit could be significant. Organizations must assess their exposure and act swiftly to mitigate risks.
Given the high CVSS score, organizations should address this vulnerability in their priority patch cycle. The urgency is further emphasized by the potential for exploitation through user interaction, making user awareness and training critical.
