Information disclosure via verbose API error messages

Published Oct 1, 2026 · Updated Oct 1, 2026

Information disclosure in HCL BigFix Service Management 27 allows remote attackers to read sensitive data through malformed API requests. Certain API endpoints include sensitive information in error messages when they receive invalid input; HCL has not identified the endpoints or the data exposed. The published assessment requires no authentication, but the reported effect is limited to disclosure from error responses, not data modification or service interruption.
