CVE-2025-9453 is an out-of-bounds read vulnerability classified under CWE-125 affecting Autodesk Shared Components version 2026.0. The vulnerability is triggered when the software parses a maliciously crafted PRT file, a common file format used in Autodesk's CAD applications. This malformed input causes the software to read memory outside the intended buffer boundaries, which can lead to multiple adverse outcomes. These include application crashes (denial of service), unauthorized disclosure of sensitive information from adjacent memory, or even arbitrary code execution within the context of the current process. The vulnerability requires user interaction, specifically opening or importing the malicious PRT file, but does not require any prior authentication or elevated privileges, making it accessible to attackers who can trick users into opening such files. The CVSS v3.1 base score is 7.8, reflecting high severity due to the potential for full compromise of confidentiality, integrity, and availability. The attack vector is local (AV:L), meaning the attacker must have local access or convince a user to open the file. Autodesk has not yet released patches, and no known exploits are publicly reported. The vulnerability affects a widely used component in Autodesk’s product suite, which is prevalent in industries relying on CAD software for design and manufacturing workflows.

For European organizations, the impact of CVE-2025-9453 can be significant, especially in sectors such as automotive, aerospace, industrial manufacturing, and architecture, where Autodesk products are heavily used. Exploitation could lead to unauthorized disclosure of intellectual property or sensitive design data, potentially causing competitive disadvantage or regulatory compliance issues under GDPR if personal data is exposed. The ability to execute arbitrary code could allow attackers to establish persistence, move laterally within networks, or deploy ransomware, severely disrupting business operations. The requirement for user interaction means phishing or social engineering campaigns could be leveraged to deliver malicious PRT files. The vulnerability also poses risks to the integrity of design files, which could lead to flawed products or safety hazards if exploited undetected. Given the critical role of CAD software in European industrial supply chains, successful exploitation could have cascading effects on production and innovation.

Organizations should implement a multi-layered approach to mitigate this vulnerability. First, monitor Autodesk’s official channels for patches and apply them immediately upon release. Until patches are available, restrict the import and opening of PRT files from untrusted or unknown sources. Employ application whitelisting and sandboxing techniques to limit the execution context of Autodesk applications, reducing the impact of potential exploitation. Enhance user awareness training to recognize and avoid opening suspicious files, especially those received via email or external media. Utilize endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts, such as unexpected crashes or memory access violations. Network segmentation can limit lateral movement if a compromise occurs. Finally, maintain regular backups of critical design data to enable recovery in case of data corruption or ransomware attacks.
