CVE-2025-1091Network attack vector

Authenticated file disclosure via missing download authorization

Published Feb 25, 2025 · Updated Feb 26, 2025

Missing authorization in Tenable Identity Exposure 3.77.8 and earlier allows remote authenticated users to download protected IOA files. The product serves IOA scripts and configuration files to any signed-in account that requests a known file URL, without enforcing file-level authorization. A valid account and prior knowledge of the URL are required; the reported consequence is read-only disclosure of those files.
