CVE-2026-59708 Details
Description
The GET /api/v1/public/:accessId/portfolio endpoint in ghostfolio accepts private access IDs without validating granteeUserId filtering, allowing unauthenticated access to full portfolio data. Attackers with a private access ID can retrieve sensitive portfolio information including holdings, quantities, buy prices, and performance metrics without authentication.
A vulnerability exists in Ghostfolio versions through 3.6.0, allowing unauthorized access to private portfolio data via the public API endpoint. The issue arises because the endpoint does not properly validate access IDs, enabling unauthenticated users to retrieve sensitive information such as holdings, quantities, buy prices, and performance metrics. This flaw was introduced in version 3.0.0 and persists in the latest release.
Users can update to Ghostfolio version 3.7.0 or later, where this vulnerability has been fixed.
