Title

Apache Linkis: Arbitrary File Read via Double URL Encoding Bypass

Summary

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.

Vulnerability from github – Published: 2026-01-19 09:30 – Updated: 2026-01-21 01:03

Summary

Apache Linkis: Arbitrary File Read via Double URL Encoding Bypass

Details

A vulnerability in Apache Linkis.

Problem Description

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.

More questions about this vulnerability can be discussed here: https://lists.apache.org/list?dev@linkis.apache.org:2025-9:cve

Severity

7.5 (High)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
