CVE-2026-57485: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in Stirling-Tools Stirling-PDF
CVE-2026-57485 is a high-severity vulnerability in Stirling-Tools Stirling-PDF prior to version 2.9.0. It involves exposure of a sensitive API key (STIRLING-PDF-BACKEND-API-USER) to authenticated users with ROLE_USER privileges via the /api/v1/user/get-api-key endpoint. This key allows impersonation of an internal service account, bypassing rate limits and accessing internal endpoints. The issue is fixed in version 2.9.0.
AI Analysis
Technical Summary
Stirling-PDF versions before 2.9.0 have a vulnerability where the /api/v1/pipeline/handleData endpoint injects the internal API key into pipeline subrequests. Authenticated users with ROLE_USER can retrieve this key through the /api/v1/user/get-api-key endpoint. Possession of this key enables attackers to impersonate the internal service account, bypass normal rate limits, and access sensitive internal endpoints such as /api/v1/info/requests/all and /api/v1/info/load/all. This exposure constitutes an unauthorized disclosure of sensitive information (CWE-200) and improper access control (CWE-522). The vulnerability is resolved in version 2.9.0.
Potential Impact
An authenticated user with ROLE_USER privileges can obtain the internal backend API key, allowing them to impersonate an internal service account. This enables bypassing of rate limits and unauthorized access to internal API endpoints, potentially exposing sensitive information and internal request data. The confidentiality impact is high, integrity impact is low, and availability is not affected.
Mitigation Recommendations
Upgrade Stirling-PDF to version 2.9.0 or later, where this vulnerability is fixed. No other mitigation is indicated or required according to the available data.
