CVE-2025-54260 is a high-severity out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Modeler versions 1.22.2 and earlier. The vulnerability arises when the software parses a specially crafted file, causing it to read beyond the allocated memory boundaries. This memory corruption can be leveraged by an attacker to execute arbitrary code within the security context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted file in the vulnerable application. The vulnerability does not expand the scope beyond the current user context, meaning it does not inherently allow privilege escalation or affect other users or system components directly. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), required user interaction (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize mitigation and monitoring. The vulnerability is significant because Adobe Substance3D - Modeler is used in 3D content creation workflows, and a successful exploit could compromise intellectual property or allow lateral movement within a compromised environment.

For European organizations, the impact of CVE-2025-54260 could be substantial, particularly for companies involved in digital content creation, gaming, media production, and industrial design that rely on Adobe Substance3D - Modeler. A successful exploit could lead to unauthorized disclosure of sensitive design files, intellectual property theft, or disruption of creative workflows. Since the vulnerability allows code execution in the context of the current user, attackers could use it as a foothold to deploy malware, conduct espionage, or move laterally within corporate networks. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files. Given the high confidentiality, integrity, and availability impacts, organizations could face operational downtime, reputational damage, and compliance issues under GDPR if sensitive data is compromised. The lack of patches at the time of disclosure increases the risk window, necessitating immediate defensive measures.

To mitigate CVE-2025-54260, European organizations should implement the following specific measures: 1) Immediately restrict the use of Adobe Substance3D - Modeler to trusted users and environments until patches are available. 2) Employ application whitelisting and sandboxing techniques to limit the execution context and prevent arbitrary code execution from untrusted files. 3) Educate users on the risks of opening files from unverified sources and implement strict email and file attachment filtering to reduce exposure to malicious files. 4) Monitor network and endpoint behavior for unusual activities indicative of exploitation attempts, such as unexpected process launches or memory access violations related to Substance3D. 5) Coordinate with Adobe for timely patch deployment once available and test updates in controlled environments before widespread rollout. 6) Consider deploying endpoint detection and response (EDR) solutions capable of detecting exploitation patterns related to out-of-bounds reads and code execution. 7) Maintain regular backups of critical design data to enable recovery in case of compromise.
