CVE-2025-13710
Published: 23 December 2025
Summary
CVE-2025-13710 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 18.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Tencent HunyuanVideo contains a deserialization of untrusted data vulnerability in the load_vae function. The flaw stems from insufficient validation of user-supplied input, enabling remote code execution on affected installations when the component processes malicious data. The issue is tracked as ZDI-CAN-27186 and carries a CVSS 7.8 score reflecting local access with required user interaction but full system impact.
An unauthenticated attacker can exploit the weakness by convincing a target to visit a malicious page or open a malicious file. Successful exploitation grants arbitrary code execution in the context of the root user.
The referenced ZDI-25-1030 advisory and the commit at https://github.com/Tencent-Hunyuan/HunyuanVideo/commit/b47e10b95483aa8458b64d23350844c29e91c408 document the fix. The EPSS score has remained flat at 0.0155 with no material increase since disclosure.

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.
