Doc Text:
A flaw was found in GluonTS. The model loading component fails to safely handle untrusted data during deserialization, which can allow an attacker to execute arbitrary commands with the privileges of the running process. An attacker can exploit this issue by convincing a user or system to load a specially crafted serialized model directory.

Description OSIDB Bzimport 2026-09-29 15:35:21 UTC
Deserialization of untrusted data in the model loading component in Amazon GluonTS before 0.17.0 might allow context-dependent attackers to execute arbitrary operating system commands with the privileges of the loading process via a crafted serialized model directory.



To remediate this issue, users should upgrade to version 0.17.0 or later.
