CVE-2025-29847

Estado: AnalizadaAlta (7.5)—

A vulnerability in Apache Linkis.

Problem Description When using the JDBC engine and da When using the JDBC engine and data source functionality, if the URL parameter configured on the frontend has undergone multiple rounds of URL encoding, it may bypass the system's checks. This bypass can trigger a vulnerability that allows unauthorized access to system files via JDBC parameters.

Scope of Impact

This issue affects Apache Linkis: from 1.3.0 through 1.7.0.

Severity level

moderate Solution Continuously check if the connection information contains the "%" character; if it does, perform URL decoding.

Users are recommended to upgrade to version 1.8.0, which fixes the issue.
