Unauthenticated file placement via absolute path traversal

Published Aug 22, 2025 · Updated Aug 25, 2025

Dangerous file upload in Salesforce Tableau Server allows remote attackers to place files at absolute paths through Flow Editor on affected releases. Flow Editor accepts an uploaded file with an attacker-controlled absolute path that escapes its intended storage location; Salesforce has not disclosed the responsible endpoint or validation logic. The network vector requires no privileges or user interaction and affects releases before 2025.1.3, before 2024.2.12, and before 2023.3.19.
