Adobe Substance3D Painter versions 11.0.3 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 rated as high severity with a CVSS score of 7.8, indicating a significant risk to organizations that utilize this software.
The potential impact of this vulnerability includes unauthorized code execution, which could lead to data compromise or system integrity issues. Organizations using affected versions of Adobe Substance3D Painter should assess their exposure to this vulnerability and take immediate steps to mitigate the risk.
Given the requirement for user interaction, the risk may be somewhat contained; however, organizations should not underestimate the potential for exploitation through social engineering or malicious file distribution. It is critical that affected users prioritize patching their applications to prevent unauthorized access.
In light of the high CVSS score and the potential impact, organizations should address this vulnerability in their priority patch cycle. The exploitation status remains unclear, as no public exploits have been confirmed at this time.
Vulnerability Details
The vulnerability is classified under CWE-787: Out-of-bounds Write. The CVSS vector string for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. It indicates that the attack vector is local, the attack complexity is low, and no privileges are required for exploitation, but user interaction is necessary.
The affected product is Adobe Substance3D Painter, with versions prior to 11.1.2 being vulnerable. The vulnerability was published on January 13, 2026, and remains analyzed.
Technical Analysis
The root cause of this vulnerability stems from improper handling of input data, leading to out-of-bounds writes. This issue can be triggered when a user opens a specially crafted file, which can manipulate memory allocation and execution flow, allowing arbitrary code execution.
The attack vector is classified as local, which means that an attacker must have access to the user's system to exploit this vulnerability. The complexity of the attack is low, as it requires only that the victim open a malicious file, and no privileges are required for exploitation.
User interaction is indeed required, as the victim must open the malicious file for the exploit to be successful. If exploited, the impact on confidentiality, integrity, and availability is rated as high, indicating a serious risk to the affected systems.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data, unauthorized execution of arbitrary code, and possible compromise of the entire system. Given the nature of the vulnerability, it can significantly affect users who may unknowingly open malicious files.
The blast radius for this vulnerability can be substantial, especially in environments where Adobe Substance3D Painter is widely used. Organizations should consider the potential for data loss, system downtime, and the costs associated with remediation efforts.
Given the CVSS score of 7.8, organizations should prioritize patching immediately. The urgency is underscored by the fact that exploitation requires user interaction but remains a viable threat, especially in environments susceptible to social engineering attacks.
