CVE-2025-9454 is an out-of-bounds read vulnerability classified under CWE-125, discovered in Autodesk Shared Components version 2026.0. The vulnerability arises when a maliciously crafted PRT file is parsed by Autodesk products that rely on these shared components. An out-of-bounds read occurs when the software reads memory outside the intended buffer boundaries, which can lead to several adverse effects. Specifically, this vulnerability can cause the affected application to crash, potentially leading to denial of service. More critically, it can allow an attacker to read sensitive data residing in adjacent memory areas, which may include confidential project information or user credentials. Furthermore, under certain conditions, the vulnerability can be leveraged to execute arbitrary code within the context of the current process, enabling an attacker to take control of the affected system or escalate privileges. The CVSS 3.1 base score is 7.8, indicating high severity, with attack vector Local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). No known exploits have been reported in the wild yet, and no patches are currently linked, suggesting that remediation may still be pending or in development. The vulnerability was reserved in August 2025 and published in December 2025. Autodesk Shared Components are widely used in Autodesk’s CAD and design software suites, making this a significant risk for users of these products.

For European organizations, the impact of CVE-2025-9454 can be substantial, particularly in sectors heavily reliant on Autodesk products such as manufacturing, automotive, aerospace, architecture, and engineering. A successful exploit could lead to unauthorized disclosure of sensitive design files and intellectual property, potentially causing competitive disadvantage or regulatory compliance issues related to data protection. The ability to execute arbitrary code elevates the risk to system integrity and availability, possibly allowing attackers to deploy malware, ransomware, or pivot within corporate networks. Disruption of critical design workflows due to application crashes could delay projects and increase operational costs. Given the local attack vector and requirement for user interaction, the threat is more likely to materialize through targeted phishing or social engineering campaigns delivering malicious PRT files. European organizations with less mature endpoint security or insufficient user awareness training are at higher risk. The absence of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation, especially once patches are released and reverse engineering occurs.

1. Monitor Autodesk’s official channels for patches addressing CVE-2025-9454 and apply them promptly upon release. 2. Implement strict controls on file sources by restricting the acceptance and opening of PRT files from untrusted or external sources. 3. Employ application whitelisting and sandboxing techniques to limit the execution context of Autodesk products, reducing the impact of potential code execution. 4. Enhance user awareness training focusing on the risks of opening unsolicited or suspicious CAD files, emphasizing social engineering vectors. 5. Utilize endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected crashes or memory access violations. 6. Conduct regular backups of critical design data to mitigate the impact of potential data corruption or ransomware attacks stemming from exploitation. 7. Network segmentation can help contain any compromise within isolated environments, limiting lateral movement. 8. Review and harden local user permissions to minimize the ability of malicious code to escalate privileges or persist. 9. Consider deploying intrusion prevention systems (IPS) with signatures or heuristics capable of detecting malformed PRT file parsing attempts once such signatures become available.
