Overview
CVE-2026-109758 is a known-severity vulnerability. It was published on October 13, 2026.
Technical description
Perforce Helix Authentication Service (HAS) deployments that retain the shipped default SCIM bearer token are vulnerable to unauthorized access when the SCIM endpoint is reachable by an attacker. In affected versions of HAS, the installation templates contain a default credential which the installer copies into the active configuration; the installer and configuration script do not automatically replace that value with a random token. An attacker who knows the default token can authenticate to the SCIM API and perform user and group operations allowed by the configured provisioning backend.
This issue can be chained with CVE-2026-61834 in affected releases of the scim-patch dependency.
This vulnerability exists in version 2022.1 - 2025.2 of HAS however the underlying defect was removed in version 2026.1 which was released July 17th 2026. The vulnerability was identified in older versions of HAS after version 2026.1 was released.
