CVE-2025-9458 is a heap-based buffer overflow vulnerability classified under CWE-122, affecting Autodesk Shared Components version 2026.3. The vulnerability is triggered when the software parses a maliciously crafted PRT file, a file format commonly used in CAD and engineering workflows. The flaw causes memory corruption that can be exploited to execute arbitrary code with the privileges of the current process. The CVSS 3.1 score of 7.8 reflects a high severity due to the potential for complete compromise of the affected application’s confidentiality, integrity, and availability. The attack vector is local (AV:L), requiring the victim to open or process the malicious PRT file (UI:R), but no privileges or authentication are required (PR:N). This means an attacker must trick a user into opening or importing a malicious file, but once done, the attacker can run code within the Autodesk process context, potentially leading to further system compromise. Although no exploits are known in the wild yet, the vulnerability poses a significant risk due to the widespread use of Autodesk software in design and manufacturing industries. The lack of available patches at the time of publication necessitates immediate risk mitigation and monitoring. The vulnerability’s impact extends beyond the affected application, as successful exploitation could allow lateral movement or data theft within enterprise environments.

For European organizations, especially those in manufacturing, engineering, and design sectors that rely heavily on Autodesk products, this vulnerability could lead to severe operational disruptions. Exploitation could result in unauthorized code execution, data breaches involving sensitive intellectual property, and potential sabotage of design files or manufacturing processes. The confidentiality of proprietary designs and the integrity of production workflows are at risk, which could have downstream effects on supply chains and product quality. Availability may also be impacted if exploited code causes crashes or system instability. Given the critical role of CAD software in European industrial sectors, the vulnerability could have financial and reputational consequences. Additionally, the need for user interaction to trigger the exploit means that social engineering or phishing campaigns targeting employees are plausible attack vectors. Organizations with less mature cybersecurity awareness or lacking strict file handling policies are particularly vulnerable.

1. Monitor Autodesk’s official channels closely for patches addressing CVE-2025-9458 and apply them immediately upon release. 2. Implement strict file validation and sandboxing for PRT files before opening them in Autodesk products to detect and isolate potentially malicious files. 3. Enforce least privilege principles by restricting user permissions to open or import files only from trusted sources. 4. Educate users about the risks of opening unsolicited or unexpected PRT files, emphasizing caution with files received via email or external media. 5. Deploy endpoint detection and response (EDR) tools capable of identifying anomalous behaviors associated with memory corruption or code execution within Autodesk processes. 6. Use application whitelisting to limit execution of unauthorized code and monitor process behavior for signs of exploitation. 7. Maintain regular backups of critical design files and system states to enable recovery in case of compromise. 8. Consider network segmentation to isolate systems running Autodesk software from broader enterprise networks to contain potential breaches.
