Title
deepseek-ai deepseek-harness dsh index.ts reliance on untrusted inputs in a security decision
Summary
A vulnerability was identified in deepseek-ai deepseek-harness up to 0.1.5-rc.3. Impacted is an unknown function of the file packages/e2b/e2b/src/index.ts of the component dsh. The manipulation of the argument E2B_API_KEY leads to reliance on untrusted inputs in a security decision. Local access is required to approach this attack.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
