Adobe Substance3D Modeler, specifically versions 1.22.4 and earlier, is affected by an Out-of-bounds Read vulnerability. This vulnerability allows attackers to disclose sensitive information stored in memory, posing a significant risk to users. The severity of this vulnerability is classified as medium, with a CVSS score of 5.5. Organizations using affected versions should be particularly mindful of this risk, as exploitation requires user interaction through the opening of a malicious file.
As the threat landscape continues to evolve, it is crucial for organizations to understand the potential impact of vulnerabilities such as this one. The urgency for defenders to address this issue is heightened due to the nature of the attack vector, which is local, requiring user interaction. Nonetheless, the potential for sensitive information exposure makes this a vulnerability that should not be overlooked.
Organizations should prioritize patching Adobe Substance3D Modeler to mitigate risks associated with this vulnerability. Remediation efforts should focus on ensuring that all users are updated to versions that have addressed this issue, thereby reducing the likelihood of exploitation.
In summary, the Out-of-bounds Read vulnerability in Adobe Substance3D Modeler presents a medium risk that necessitates immediate attention from security teams to protect sensitive information from potential disclosure.
Vulnerability Details
The vulnerability described is classified as an Out-of-bounds Read, specifically identified as CWE-125. It affects versions 1.22.4 and earlier of Adobe Substance3D Modeler, with a CVSS v3.1 score of 5.5, indicating a medium severity level. The vulnerability was publicly disclosed on January 13, 2026, and requires user interaction for exploitation, which involves opening a specially crafted malicious file.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input, leading to an Out-of-bounds Read condition. This vulnerability is classified as having low attack complexity, as it requires no special privileges to exploit. However, successful exploitation necessitates user interaction, specifically requiring the victim to open a malicious file.
The attack vector for this vulnerability is local, meaning that the attacker must have access to the local system. In terms of impacts, the confidentiality impact is rated as high, while integrity and availability impacts are rated as none, indicating that the primary risk involves the disclosure of sensitive information rather than disruption of service or corruption of data.
Risk & Impact Analysis
The real-world risk associated with this vulnerability includes potential exposure of sensitive information stored in memory. Organizations utilizing Adobe Substance3D Modeler versions 1.22.4 and earlier should assess their deployment to understand the implications of this vulnerability. Given that the attack vector is local, the blast radius is limited to systems where the software is installed and where users may inadvertently open malicious files.
Organizations should assess the urgency of addressing this vulnerability based on their usage of affected products. The CVSS score of 5.5 suggests that while this is not the highest severity, it is still significant enough to warrant prompt attention. It is advisable for organizations to prioritize patching in their remediation cycle to prevent any potential exploitation.
