## Summary

Apache SIS's SQL storage module (sql-storage), which provides the SQL-backed feature store, is affected by this vulnerability. An attacker who can supply a crafted sort clause could inject arbitrary SQL into queries run by the feature store, potentially compromising the underlying database.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- org.apache.sis.storage:sis-sqlstore: from 1.0, through 1.6.0

## Description

Vulnerability in the SQL storage module of Apache SIS. When sorting a stream of features, the clause is copied after ORDER BY without quoting the identifier character. A crafter sort clause could inject SQL in the query. This issue affects the sql-storage module of Apache SIS from version 1.0 through 1.6 inclusive. Other modules such as sis-referencing are not impacted. Users are recommended to upgrade to version 1.7, which fixes the issue.
