GHSA-fqj2-r74g-4gfp
A vulnerability in the ghostfolio API endpoint GET /api/v1/public/:accessId/portfolio allows unauthenticated attackers possessing a private access ID to retrieve full portfolio data without proper user filtering. This includes sensitive information such as holdings, quantities, buy prices, and performance metrics. The issue stems from missing validation of the granteeUserId, enabling unauthorized access to private portfolio details.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-59708 affects the ghostfolio API endpoint GET /api/v1/public/:accessId/portfolio. The endpoint accepts private access IDs but fails to validate the granteeUserId, which should restrict access to authorized users only. As a result, attackers with knowledge of a private access ID can bypass authentication and access sensitive portfolio information including holdings, quantities, buy prices, and performance metrics. This represents a broken access control issue (CWE-862). There is no information about available patches or vendor advisories, and no known exploits in the wild have been reported.
Potential Impact
Unauthorized disclosure of sensitive portfolio data including holdings, quantities, buy prices, and performance metrics. This could lead to privacy violations and potential financial information leakage. The vulnerability allows unauthenticated access, increasing the risk of data exposure without requiring user credentials.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected API endpoint by implementing additional access controls or network-level protections to prevent unauthorized use of private access IDs.
