CVE-2026-73325 (GCVE-0-2026-73325)

Vulnerability from nvd – Published: 2026-08-12 15:35 – Updated: 2026-08-12 19:19

Title

Fujitsu OneCompression 1.2.0 Arbitrary Code Execution via torch.load Deserialization

Summary

Fujitsu Research's OneCompression library 1.2.0 contains an unsafe deserialization vulnerability that allows attackers to execute arbitrary code by supplying a crafted model.pt checkpoint file, as QuantizedModelLoader.load_quantized_model_pt() unconditionally calls torch.load with weights_only=False, invoking Python's pickle machinery during deserialization. Attackers can embed malicious __reduce__ methods in a crafted model checkpoint to execute arbitrary Python code, including system commands, when the library loads the file from a caller-selected model directory.
