CVE-2025-13716 is a critical vulnerability identified in Tencent MimicMotion, specifically within the create_pipeline function. The root cause is the deserialization of untrusted data (CWE-502), where the application fails to properly validate or sanitize user-supplied input before deserializing it. This improper handling allows an attacker to craft malicious serialized objects that, when processed by the vulnerable function, lead to arbitrary code execution. The vulnerability is exploitable remotely but requires user interaction, such as the victim visiting a malicious webpage or opening a crafted file. Successful exploitation grants the attacker code execution with root privileges, enabling full system compromise. The CVSS 3.0 score of 7.8 indicates high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No patches have been publicly released yet, and no known exploits are reported in the wild. The vulnerability was reserved and published by the Zero Day Initiative (ZDI) under the identifier ZDI-CAN-27208. Given the critical nature of the flaw and root-level code execution, it represents a significant threat to affected systems.

For European organizations, the impact of CVE-2025-13716 can be severe. Successful exploitation allows attackers to gain root-level control over affected systems running Tencent MimicMotion, potentially leading to full system compromise, data theft, disruption of services, and lateral movement within networks. This can affect confidentiality by exposing sensitive data, integrity by allowing unauthorized modification of data or system configurations, and availability by enabling denial-of-service conditions or destruction of critical resources. Organizations in sectors such as technology development, media, and any industry relying on Tencent MimicMotion for animation or motion capture workflows are at risk. The requirement for user interaction means social engineering or phishing campaigns could be used to trigger exploitation, increasing the attack surface. The lack of available patches heightens the urgency for defensive measures. Additionally, the root-level execution capability makes recovery and remediation more complex and costly.

1. Immediate mitigation should focus on restricting access to Tencent MimicMotion installations, especially limiting exposure to untrusted networks and users. 2. Implement strict input validation and sanitization on all data inputs related to the create_pipeline function to prevent deserialization of malicious objects. 3. Employ application-layer firewalls or intrusion prevention systems (IPS) to detect and block suspicious serialized data patterns. 4. Educate users about the risks of opening files or visiting links from untrusted sources to reduce the likelihood of user interaction exploitation. 5. Monitor system and application logs for unusual activity indicative of exploitation attempts, such as unexpected process executions or privilege escalations. 6. Segment networks to isolate critical systems running Tencent MimicMotion, limiting lateral movement in case of compromise. 7. Stay alert for official patches or updates from Tencent and apply them promptly once available. 8. Consider deploying endpoint detection and response (EDR) solutions capable of identifying anomalous behavior related to deserialization attacks. 9. Conduct regular security assessments and penetration testing focusing on deserialization vulnerabilities and user interaction attack vectors.
