Detailsinfo

A vulnerability was found in CyferShepard Jellystat up to 1.1.9. It has been rated as critical. This issue affects some unknown functionality of the file /api/getUserDetails of the component API Endpoint. The manipulation with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Jellystat is a free and open source Statistics App for Jellyfin. Prior to version 1.1.10, multiple API endpoints in Jellystat build SQL queries by interpolating unsanitized request-body fields directly into raw SQL strings. An authenticated user can inject arbitrary SQL via `POST /api/getUserDetails` and `POST /api/getLibrary`, enabling full read of any table in the database - including `app_config`, which stores the Jellystat admin credentials, the Jellyfin API key, and the Jellyfin host URL. Because the vulnerable call site dispatches via `node-postgres`'s simple query protocol (no parameter array is passed), stacked queries are allowed, which escalates the injection from data disclosure to arbitrary command execution on the PostgreSQL host via `COPY ... TO PROGRAM`. Under the role shipped by the project's `docker-compose.yml` (a PostgreSQL superuser), no additional privileges are required to reach the RCE primitive. Version 1.1.10 contains a fix.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-41167 since 04/17/2026. The exploitation is known to be easy. The attack may be initiated remotely. The exploitation needs additional levels of successful authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1505 for this issue.

Upgrading to version 1.1.10 eliminates this vulnerability. Applying the patch 735fe7c6eb0e3e34e92a8a82fd21914d76693665 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
