Vulnerability from github – Published: 2026-04-17 18:31 – Updated: 2026-04-24 21:31

Details

OpenHarness before commit bd4df81 contains a permission bypass vulnerability that allows attackers to read sensitive files by exploiting incomplete path normalization in the permission checker. Attackers can invoke the built-in grep and glob tools with sensitive root directories that are not properly evaluated against configured path rules, allowing disclosure of sensitive local file content, key material, configuration files, or directory contents despite configured path restrictions.

Severity

7.5 (High)

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.
