CVE-2025-10899 is an out-of-bounds write vulnerability classified under CWE-787, affecting Autodesk Shared Components version 2026.0. This vulnerability is triggered when a maliciously crafted MODEL file is parsed by certain Autodesk products that rely on these shared components. The out-of-bounds write can lead to memory corruption, which attackers may exploit to cause application crashes, data corruption, or execute arbitrary code with the privileges of the current user process. The vulnerability requires user interaction (opening or importing the malicious MODEL file) and has a low attack complexity, meaning it does not require sophisticated conditions to exploit. No privileges are required to exploit this vulnerability, increasing its risk profile. The CVSS v3.1 base score is 7.8, indicating a high severity level due to its impact on confidentiality, integrity, and availability. Autodesk Shared Components are integral to multiple Autodesk software suites widely used in design, engineering, and construction industries. Although no exploits are currently reported in the wild, the vulnerability poses a significant risk if weaponized. The absence of available patches at the time of reporting necessitates proactive mitigation strategies. The vulnerability was reserved in September 2025 and published in December 2025, reflecting a recent discovery and disclosure timeline.

The vulnerability can have severe impacts on organizations using Autodesk products that incorporate the affected Shared Components. Successful exploitation can lead to arbitrary code execution, allowing attackers to take control of the affected system under the current user's privileges. This can result in unauthorized access to sensitive design files, intellectual property theft, or sabotage of critical engineering data. Data corruption or application crashes can disrupt workflows, leading to downtime and potential financial losses. Given the widespread use of Autodesk software in critical sectors such as architecture, engineering, construction, and manufacturing, the impact extends to operational continuity and data integrity. Organizations lacking timely patching or mitigation may face increased risk of targeted attacks, especially from threat actors aiming to compromise design and infrastructure projects. The requirement for user interaction limits remote exploitation but does not eliminate risk, particularly in environments where users frequently exchange MODEL files. The absence of known exploits in the wild currently reduces immediate threat but does not preclude future exploitation attempts.

Organizations should implement the following specific mitigation measures: 1) Monitor Autodesk’s official channels for patches addressing CVE-2025-10899 and apply updates promptly once available. 2) Enforce strict validation and scanning of MODEL files before opening or importing them, using sandbox environments or isolated virtual machines to analyze untrusted files. 3) Educate users on the risks of opening MODEL files from unverified sources and implement policies restricting file sharing from external or unknown origins. 4) Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior indicative of exploitation attempts. 5) Limit user privileges on systems running Autodesk products to reduce the impact of potential code execution. 6) Utilize network segmentation to isolate critical design and engineering systems from general user networks, minimizing lateral movement opportunities. 7) Maintain regular backups of critical design data to enable recovery in case of data corruption or ransomware attacks leveraging this vulnerability. These targeted actions go beyond generic advice by focusing on the specific attack vector and environment.
