CVE-2024-4456Network attack vector

Stored XSS via unneutralized audit-page payload

Published May 8, 2024 · Updated Jan 16, 2025

Stored XSS in affected Octopus Deploy Octopus Server releases allows remote authenticated users to execute script through the audit page. The audit page stores and renders an embedded cross-site scripting payload without neutralizing executable browser content. High-privilege access is required; successful exploitation runs stored code in the audit-page browser context and can read or alter browser-accessible data.
