CVE-2026-67100 describes two vulnerabilities in HCL BigFix Service Management version 23: an SQL Injection (CWE-89) flaw and a Cross-Tenant Data Exposure (CWE-200) flaw. The SQL Injection vulnerability enables an authenticated attacker to inject database commands, potentially extracting sensitive system information. The Cross-Tenant Data Exposure vulnerability allows manipulation of request values to gain unauthorized access to full personal profile data and personally identifiable information (PII) across different organizations using the service. The CVSS 3.1 base score is 9.8, indicating critical severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.

Successful exploitation could lead to unauthorized disclosure of sensitive system details and personal data across tenant boundaries, compromising confidentiality, integrity, and availability of the affected system and data. This poses a significant risk to data privacy and system security for organizations using HCL BigFix Service Management version 23.
