Thomson Reuters recognizes that security vulnerabilities in software deployed within our own environments, or within our customer environments can pose significant risk. We conduct daily vulnerability scans of ONESOURCE Determination application code and dependencies. ONESOURCE Determination Anywhere container images are scanned daily to identify and remediate security vulnerabilities. While we strive to address zero-day vulnerabilities as rapidly as possible, remediation timelines follow the Thomson Reuters Information Security & Risk Management (ISRM) guidelines based on severity classifications identified by our scanning tool, Snyk – Critical (30 days), High (60 days), Medium & Low (best-effort basis in a future release). If vulnerabilities are found after software is released, Critical issues are fixed through urgent Production releases or in the next scheduled release cycle. We aim to uphold our commitment to providing secure solutions.

Determination Anywhere (DA) 2026.06 patch addresses an issue with data sync.

The following topics outline previously identified issues that have been resolved in this release.

A full content import could fail and roll back for tenants with certain custom Product Category configurations, preventing the latest tax content from being applied. This occurred when duplicate Product Category and Authority combinations were detected during the import due to differences between tenant configuration and shared content records.

With this update, Product Authorities, Authority Types, and Product Zones now use the tenant configuration as the single source of truth, eliminating the duplicate records that caused the import failure. This fix allows affected full content imports to complete successfully, helping ensure tenant tax content remains current without requiring customers to delete and recreate their custom Product Categories.
