EverShop is a TypeScript-first eCommerce platform. During category update and deletion event handling, the application embeds path / requestpath values—derived from the urlkey stored in the database—into SQL statements via string concatenation and passes them to execute(). As a result, if a malicious string is stored in urlkey , subsequent event processing modifies and executes the SQL statement, leading to a second-order SQL injection. Patched from v2.1.1.

A Blind Server-Side Request Forgery (SSRF) vulnerability in evershop 2.1.0 and prior allows unauthenticated attackers to force the server to initiate an HTTP request via the "GET /images" API. The vulnerability occurs due to insufficient validation of the "src" query parameter, which permits arbitrary HTTP or HTTPS URIs, resulting in unexpected requests against internal and external networks.

A Denial of Service (DoS) vulnerability in evershop 2.1.0 and prior allows unauthenticated attackers to exhaust the application server's resources via the "GET /images" API. The application fails to limit the height of the use-element shadow tree or the dimensions of pattern tiles during the processing of SVG files, resulting in unbounded resource consumption and system-wide denial of service.
