Summary

A vulnerability in ESPnet up to 202610.post2 affects the build_model function in espnet3/publication/inference_model.py of the Inference Model Handler component. Manipulation of the _target_ argument results in deserialization, and the attack can be launched remotely. The exploit has been made public, and the patch is identified as f217b24f06de55e332cab10231469d5890dbbe00.

Risk Assessment

Remote deserialization may enable arbitrary code execution on the server, leading to full system compromise. The public availability of the exploit increases the risk of rapid exploitation.

Recommendation

Apply patch f217b24f06de55e332cab10231469d5890dbbe00 or update ESPnet to a version containing this fix.

Other vulnerabilities in ESPnet

CVE-2026-90777High
ESPnet before 202609 deserializes pretrained model checkpoints using torch.load with weights_only=False, allowing arbitrary code execution from attacker-supplied files. Attackers can craft malicious checkpoint files that execute code during deserialization when loaded through the initialization or fine-tuning path.

Original NVD description (English source)

A vulnerability was found in ESPnet up to 202610.post2. This affects the function build_model of the file espnet3/publication/inference_model.py of the component Inference Model Handler. The manipulation of the argument _target_ results in deserialization. It is possible to launch the attack remotely. The exploit has been made public and could be used. The patch is identified as f217b24f06de55e332cab10231469d5890dbbe00. It is best practice to apply a patch to resolve this issue.
