CVE-2025-10889 is a classic buffer overflow vulnerability (CWE-120) identified in Autodesk Shared Components version 2026.0. This vulnerability occurs due to a lack of proper bounds checking when parsing CATPART files, which are proprietary CAD part files used by Autodesk products. A specially crafted CATPART file can trigger memory corruption, allowing an attacker to overwrite memory buffers and potentially execute arbitrary code within the context of the affected process. The vulnerability requires the victim to open or process the malicious CATPART file, implying user interaction is necessary. No prior privileges are required to exploit this flaw, but the attack vector is local (AV:L), meaning the attacker must have access to deliver the malicious file to the victim. The CVSS v3.1 base score is 7.8, indicating high severity with high impact on confidentiality, integrity, and availability. The vulnerability was published on December 15, 2025, with no known exploits in the wild and no patches released at the time of publication. Autodesk Shared Components are widely used in various Autodesk CAD applications, which are prevalent in design, engineering, and manufacturing industries. This vulnerability poses a significant risk as it can lead to arbitrary code execution, potentially allowing attackers to take control of affected systems or disrupt critical design workflows. The lack of patch availability necessitates immediate mitigation through operational controls and monitoring.

For European organizations, especially those in manufacturing, engineering, architecture, and industrial design sectors, this vulnerability presents a substantial risk. Exploitation could lead to unauthorized code execution, resulting in data theft, intellectual property compromise, or disruption of critical design and manufacturing processes. Given the reliance on Autodesk products in Europe’s industrial and engineering sectors, successful exploitation could impact operational continuity and confidentiality of sensitive design data. The requirement for user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks, especially spear-phishing or supply chain vectors delivering malicious CATPART files. The high impact on confidentiality, integrity, and availability means that affected organizations could face significant financial and reputational damage. Additionally, disruption in design workflows could delay production and project timelines, affecting competitiveness. The absence of patches increases exposure until Autodesk releases updates, emphasizing the need for proactive defense measures.

1. Restrict the handling of CATPART files to trusted sources only; implement strict file validation and scanning before opening. 2. Employ application whitelisting to limit execution of unauthorized or unexpected processes spawned by Autodesk applications. 3. Educate users about the risks of opening CATPART files from untrusted or unknown sources to reduce the chance of social engineering exploitation. 4. Monitor Autodesk application processes for anomalous behavior indicative of exploitation attempts, such as unexpected memory usage or process spawning. 5. Use endpoint detection and response (EDR) tools to detect and block suspicious activities related to memory corruption or code injection. 6. Isolate critical design workstations in segmented network zones to limit lateral movement if exploitation occurs. 7. Prepare for rapid deployment of patches once Autodesk releases a fix; maintain close communication with Autodesk security advisories. 8. Implement strict access controls and logging around file shares and repositories where CATPART files are stored or exchanged. 9. Consider sandboxing or opening CATPART files in controlled environments to detect malicious behavior before use in production. 10. Regularly back up critical design data to enable recovery in case of compromise or disruption.
