CVE-2026-22584Public exploitNetwork attack vector

Arbitrary code execution via unvalidated model metadata

Published Jan 9, 2026 · Updated Jan 9, 2026

Code injection in Salesforce Uni2TS 1.2.0 and earlier allows attackers to execute arbitrary code when a crafted model is loaded. The decode_distr_output functions pass attacker-controlled target values from a model repository's config.json to hydra.utils.instantiate without restricting the callable. Execution occurs when MoiraiModule.from_pretrained() or MoiraiMoEModule.from_pretrained() loads the model, so a malicious or compromised model source is required.
