CyberRota Analysis

AI-Generated

APITable versions up to 1.13.0-beta.1 are vulnerable due to an incorrect authorization flaw in the NodePermissionGuard, which fails to enforce node-level access control when exceptions occur during permission checks. This allows attackers with valid Fusion API tokens to write attachments to private datasheets that they should not have access to, potentially leading to data leakage or unauthorized modifications. Organizations utilizing APITable should prioritize addressing this vulnerability to safeguard sensitive data from unauthorized access.

Original NVD Description

APITable through 1.13.0-beta.1 contains an incorrect authorization vulnerability in NodePermissionGuard that fails to enforce node-level access control when permission lookups throw exceptions. Attackers with valid Fusion API tokens can write attachments to private datasheets they have been explicitly denied access to by exploiting the unhandled exception in the permission guard.
