Low risk13th percentile - higher than 13% of all known CVEs
Summary
HCL Hive is affected by an information exposure vulnerability where Swagger documentation was found exposed publicly. Although no sensitive information (e.g., credentials, PII) was discovered, exposing API documentation to unauthenticated users can increase the overall attack surface.
Risk Assessment
Publicly exposing API documentation may help attackers understand the system structure and find potential attack vectors.
Recommendation
Restrict access to Swagger documentation to authorized users only or hide it entirely in production environments.
Other vulnerabilities in HCL Hive
See all- CVE-2026-21758Low
HCL Hive is affected by an information disclosure vulnerability, which could lead to an attacker gathering sensitive information about the host environment.
- CVE-2026-21754Medium
HCL Hive is affected by multiple infrastructure and network configuration vulnerabilities, which could lead to unauthorized lateral movement, container breakout, and sensitive data exposure within internal communications.
- CVE-2026-21753Medium
