CVE-2026-25811Network attack vector

Cross-tenant data access via unverified email domains

Published Feb 9, 2026 · Updated Feb 9, 2026

Incorrect authorization in Praskla Technology PlaciPy 1.0.0 allows remote authenticated users to access cross-tenant data. The tenant-selection logic treats the user-supplied email domain as the tenant identifier without verifying domain ownership or registration. A low-privileged account can therefore be associated with another institution's tenant and read its data; no write impact is published.
