CVE-2026-21783

HCL Traveler is affected by sensitive information disclosure.

MEDIUM 4.3EPSS 0.29%

Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

HCL Traveler is affected by sensitive information disclosure.  The application generates some error messages that provide detailed information about errors and failures, such as internal paths, file names, sensitive tokens, credentials, error codes, or stack traces.  Attackers could exploit this information to gain insights into the system's architecture and potentially launch targeted attacks.
