CVE-2025-13713
Published: 23 December 2025
Summary
CVE-2025-13713 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Zerodayinitiative (inferred from references). Its CVSS base score is 7.8 (High).
Operationally, ranked in the top 19.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Tencent Hunyuan3D-1 contains a deserialization of untrusted data vulnerability in the load_pretrained function. The flaw stems from insufficient validation of user-supplied input, enabling remote code execution on affected installations when the function processes malicious serialized data. The issue is tracked as ZDI-CAN-27191 and carries a CVSS 3.0 score of 7.8 with CWE-502.
Remote attackers can exploit the vulnerability by supplying a crafted file or directing a victim to a malicious page that triggers load_pretrained. Successful exploitation grants arbitrary code execution with root privileges, though user interaction is required to open the file or visit the page.
The referenced GitHub commit addresses the flaw in the load_pretrained implementation, while the Zero Day Initiative advisory ZDI-25-1027 provides additional technical details for affected deployments. The associated EPSS score remains low and unchanged at 0.0136 with no observed upward trajectory after disclosure.

a malicious page or open a malicious file. The specific flaw exists within the load_pretrained function. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-27191.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
