CVE-2026-11904Network attack vector

Unauthenticated information disclosure via detailed browser errors

Published Jul 30, 2026 · Updated Jul 30, 2026

Information disclosure in affected IBM Verify Access products allows remote attackers to read sensitive data via browser error messages. An unspecified web-facing component returns detailed technical errors containing sensitive system information instead of a sanitized response. No authentication or user interaction is required; the confidentiality-only disclosure provides information usable in further attacks.
