There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability in HCL DominoIQ (version 14.5.1) involves missing authorization checks (CWE-862) in the RAG feature. Specifically, document-level access controls can be ignored during AI query data retrieval, enabling authenticated attackers to view sensitive information beyond their access rights. The CVSS 3.1 base score of 6.5 reflects a network attack vector with low attack complexity, requiring privileges but no user interaction, and impacts confidentiality without affecting integrity or availability.
Potential Impact
An authenticated attacker could bypass document-level access restrictions in DominoIQ 14.5.1, potentially exposing sensitive data that should be protected. This compromises confidentiality but does not affect data integrity or availability. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, organizations should consider restricting access to the affected feature to trusted users only and monitor for unusual access patterns related to AI query usage.
