CVE-2026-11927Network attack vectorHinoki check available

Outbound request manipulation via parameter injection

Published Sep 15, 2026 · Updated Sep 15, 2026

Parameter injection in IBM Verify Identity Access and IBM Security Verify Access reverse proxies lets attackers alter third-party requests. IBM has not disclosed which reverse-proxy handler accepts the untrusted parameters or how it incorporates them into outbound requests. Public records do not state whether authentication is required, so exposure depends on which actors can submit input to an affected integration.
