CVE-2025-54195 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Substance3D - Painter versions 11.0.2 and earlier. This vulnerability arises when the software improperly handles memory bounds during processing of certain input data, allowing an attacker to read memory outside the intended buffer boundaries. Exploitation requires user interaction, specifically that a victim opens a maliciously crafted file within the application. Successful exploitation can lead to disclosure of sensitive memory contents, potentially exposing confidential information such as credentials, cryptographic keys, or other sensitive data residing in adjacent memory regions. The vulnerability does not allow modification of data or denial of service but compromises confidentiality. The CVSS 3.1 base score is 5.5 (medium severity), reflecting that the attack vector is local (AV:L), requires 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. There are no known exploits in the wild at this time, and no patches have been linked yet. Given the nature of the vulnerability, it is likely triggered by opening malicious files specifically crafted to exploit the out-of-bounds read condition in Substance3D - Painter's file parsing or rendering components.

For European organizations, the impact of CVE-2025-54195 primarily concerns confidentiality breaches. Organizations using Adobe Substance3D - Painter, especially in industries such as digital content creation, gaming, advertising, and media production, could face exposure of sensitive intellectual property or internal data if malicious files are opened by users. Since exploitation requires user interaction, the risk is mitigated somewhat by user awareness and controlled file handling policies. However, targeted spear-phishing or supply chain attacks delivering malicious Substance3D project files could lead to data leakage. The vulnerability does not affect system integrity or availability, so operational disruption is unlikely. Still, disclosure of sensitive memory contents could aid attackers in further attacks or espionage, particularly in creative studios or agencies handling confidential client projects. The medium severity score suggests moderate risk, but the potential for sensitive data exposure warrants attention in environments where Substance3D - Painter is widely used.

1. Implement strict file handling policies: Only open Substance3D - Painter project files from trusted sources. 2. Educate users on the risks of opening unsolicited or unexpected files, especially those received via email or external media. 3. Employ network-level controls to scan and block potentially malicious files before reaching end users. 4. Monitor Adobe's security advisories closely for official patches or updates addressing this vulnerability and apply them promptly once available. 5. Consider sandboxing or running Substance3D - Painter in isolated environments to limit potential data exposure. 6. Use endpoint detection and response (EDR) solutions to detect anomalous behavior that might indicate exploitation attempts. 7. Maintain regular backups and ensure sensitive data is encrypted at rest and in memory where possible to reduce impact of any data leakage.
