CVE-2026-113743 Details
Description
A weakness has been identified in Tenstorrent tt-metal up to 0.80.0. The affected element is the function load_hf_state_dict_filtered of the file models/tt_transformers/tt/load_checkpoints.py. This manipulation of the argument weight_map causes path traversal. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 0.81.0-dev20261016 is sufficient to fix this issue. Patch name: 4851ccf347f6903c3d819eed60705600386e52c3. It is suggested to upgrade the affected component.
A path traversal vulnerability has been identified in Tenstorrent tt-metal versions through 0.80.0. The issue arises in the checkpoint loading function, where shard filenames from the model's index are joined with the checkpoint directory using os.path.join() without proper validation. This flaw allows a malicious model package to read files from outside the designated directory and inject their contents as tensor values into the model, effectively tampering with the model's weights. The vulnerability can be exploited remotely, and a public exploit is available.
Users are advised to upgrade to Tenstorrent tt-metal version 0.81.0-dev20261016, where this vulnerability has been fixed.
