CVE-2026-113743 — Tenstorrent tt-metal load_checkpoints.py load_hf_state_dict_filtered path traversal

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+6
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Tenstorrent Tt-metal).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  5. Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2026-113743 is "Tenstorrent tt-metal load_checkpoints.py load_hf_state_dict_filtered path traversal", rated Medium. It affects Tt-metal (Tenstorrent); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 6.3 describes technical severity. EPSS 0.44% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
