Vulnerability from github – Published: 2026-05-20 15:35 – Updated: 2026-05-20 15:35

Details

The HCL DominoIQ RAG feature is affected by a Broken Access Control vulnerability. Under certain circumstances, document level access restrictions will be ignored when determining what data to return from an AI query. This could enable an authenticated attacker to view sensitive data.

Severity

6.5 (Medium)

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.
