CVE-2026-96803 Details
Description
A vulnerability was identified in java110 MicroCommunity up to 2.0. Affected is the function QueryServiceSMOImpl.fallBack of the file BusinessApi.java of the component fallBack API Endpoint. Such manipulation of the argument fallBackSql leads to sql injection. The attack may be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
A critical unauthenticated SQL injection vulnerability has been identified in java110 MicroCommunity versions through 2.0. The issue resides in the fallBack API endpoint of the QueryServiceSMOImpl class, where raw SQL is extracted from the request body and executed without proper validation or parameterization. This vulnerability is accessible to any unauthenticated client over the internet, allowing for arbitrary SQL execution and potential database exfiltration. Furthermore, it can be escalated to remote code execution by manipulating specific database fields.
To address this vulnerability, the JwtFilter URL pattern registration should be updated to a default-deny policy, removing the generic SQL execution nodes from the MyBatis mapper, and refactoring the fallBack method to use whitelisting and parameterization. Additionally, database privileges should be minimized to prevent unauthorized DDL operations.
