CVE-2025-9456 is a memory corruption vulnerability classified under CWE-787 (Out-of-bounds Write) affecting Autodesk Shared Components version 2026.0. The vulnerability is triggered when the software parses a specially crafted SLDPRT file, a common file format used for 3D CAD models. The out-of-bounds write leads to memory corruption, which an attacker can leverage to execute arbitrary code within the context of the current process. This means that if a user opens or previews a malicious SLDPRT file, the attacker could gain the same privileges as the user running the Autodesk application. The CVSS v3.1 score of 7.8 reflects a high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), and user interaction required (UI:R). The vulnerability impacts confidentiality, integrity, and availability, as arbitrary code execution can lead to data theft, modification, or denial of service. No public exploits are reported yet, but the vulnerability is publicly disclosed and should be considered a significant risk. The lack of available patches at the time of publication necessitates immediate risk mitigation through other controls. Autodesk Shared Components are widely used across Autodesk’s product suite, making this vulnerability relevant to many users who handle CAD files, especially in professional and industrial contexts.

For European organizations, the impact of CVE-2025-9456 is substantial due to the widespread use of Autodesk products in sectors such as automotive, aerospace, manufacturing, architecture, and engineering. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to intellectual property theft, sabotage of design files, or disruption of critical design workflows. This could result in financial losses, reputational damage, and operational downtime. Given that the vulnerability requires user interaction but no elevated privileges, phishing or social engineering campaigns could be used to trick users into opening malicious files. The high confidentiality impact is critical for organizations that rely on proprietary designs and sensitive project data. Integrity and availability impacts also pose risks to project timelines and product quality. European organizations with less mature cybersecurity practices or insufficient endpoint protections are particularly vulnerable. Additionally, the lack of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high.

1. Monitor Autodesk’s official channels for patches addressing CVE-2025-9456 and apply them immediately upon release. 2. Until patches are available, restrict the opening of SLDPRT files from untrusted or unknown sources through policy enforcement and user training. 3. Implement application whitelisting to limit execution of unauthorized code within Autodesk environments. 4. Use sandboxing or containerization technologies to isolate Autodesk applications, reducing the impact of potential exploitation. 5. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts. 6. Educate users about the risks of opening unsolicited CAD files and encourage verification of file sources. 7. Review and tighten file handling permissions and network segmentation to limit lateral movement if compromise occurs. 8. Conduct regular security assessments of CAD environments to identify and remediate related vulnerabilities or misconfigurations. These targeted measures go beyond generic advice by focusing on the specific attack vector (malicious SLDPRT files) and the operational context of Autodesk products.
