Helix Authentication Service
Monthly
Unauthorized SCIM API access in Perforce Helix Authentication Service (HAS) versions 2022.1 through 2025.2 arises from a shipped default bearer token that the installer and configuration script fail to rotate, enabling remote, unauthenticated attackers who know the token to perform user and group provisioning operations. Chaining this with CVE-2026-61834 in the scim-patch dependency allows server-side prototype pollution and, under Node.js 24/Express with specific gadget chains, remote code execution. The underlying defect is removed in HAS 2026.1; no public exploit code has been identified at time of analysis.
