CVE-2025-54205 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Sampler versions 5.0.3 and earlier. This vulnerability arises when the software improperly handles memory bounds while processing certain data structures, leading to the potential disclosure of sensitive memory contents. Exploitation requires user interaction, specifically that a victim opens a maliciously crafted file designed to trigger the out-of-bounds read. The vulnerability does not allow modification of data or denial of service but can expose confidential information residing in adjacent memory regions. The CVSS v3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), requires low attack complexity (AC:L), no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to confidentiality (C:H), with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been released yet. The vulnerability is specific to Adobe's Substance3D - Sampler, a 3D texturing and material authoring tool widely used in creative industries for digital content creation.

For European organizations, particularly those in creative sectors such as gaming, film production, advertising, and digital design, this vulnerability poses a risk of sensitive data leakage. The exposed memory could contain proprietary project data, user credentials, or other confidential information, potentially leading to intellectual property theft or privacy violations. Since exploitation requires opening a malicious file, targeted spear-phishing or supply chain attacks could be vectors for compromise. The impact is more pronounced for organizations that heavily rely on Adobe Substance3D - Sampler in their workflows. While the vulnerability does not allow code execution or system compromise, the confidentiality breach could undermine trust, cause reputational damage, and lead to compliance issues under GDPR if personal data is exposed.

Organizations should implement strict file handling policies, including restricting the opening of files from untrusted or unknown sources within Adobe Substance3D - Sampler. Employing sandboxing or isolated environments for opening files can limit exposure. Monitoring and educating users about spear-phishing and malicious file risks is critical. Since no patches are currently available, consider temporarily limiting the use of affected versions or substituting with alternative tools where feasible. Network segmentation and endpoint detection solutions can help identify anomalous behaviors related to file handling. Additionally, organizations should maintain up-to-date backups and incident response plans tailored to data leakage scenarios. Close coordination with Adobe for timely patch deployment once available is essential.
