CVE-2026-113743 - Vulnerability Details

- Tenstorrent tt-metal load_checkpoints.py load_hf_state_dict_filtered path traversal

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.

Analysis

Impact

The vulnerability resides in the load_hf_state_dict_filtered function of the tt-metal library, where unsanitized manipulation of the weight_map argument allows an attacker to specify file paths that traverse outside the intended directory. This path traversal can enable read access to arbitrary files on the host, compromising confidentiality. The flaw is identified as CWE‑22.

Affected Systems

Tenstorrent tt‑metal prior to the release 0.81.0‑dev20261016 is affected. Any installation that includes the models/tt_transformers/tt/load_checkpoints.py module with the vulnerable load_hf_state_dict_filtered function may be susceptible.

Risk and Exploitability

The CVSS score of 5.3 classifies the issue as moderate severity. The EPSS score is below 1%, indicating a low probability of widespread exploitation at present. The vulnerability is not listed in the CISA KEV catalog. According to the description, the exploit is publicly available and can be triggered remotely by supplying a specially crafted weight_map to the restricted function.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade Tenstorrent tt-metal to v0.81.0‑dev20261016 or apply the patch with commit 4851ccf347f6903c3d819eed60705600386e52c3.
If an upgrade is not immediately feasible, enforce input validation on the weight_map parameter to reject paths containing path traversal sequences such as '../' or absolute paths.
Restrict remote invocation of load_hf_state_dict_filtered by limiting network accessibility or requiring authentication, ensuring only trusted systems can call the function.
After applying the patch or implementing the validation, restart or reload any services that use tt-metal to ensure the updated code is active.
