Can you explain this vulnerability to me?

CVE-2026-7678 is a high-severity SQL injection vulnerability found in the YunaiV yudao-cloud project, specifically in the GoView component's getDataBySQL method within the GoViewDataServiceImpl.java file.

The vulnerability arises because this method executes user-provided SQL queries directly without proper parameterization or input validation, only checking that the input is non-empty.

This flaw allows authenticated users with the report:go-view-data:get-by-sql permission to inject malicious SQL code remotely.

How can this vulnerability impact me? :

This vulnerability can lead to unauthorized data access, data manipulation, or even complete compromise of the database.

Attackers can exploit this flaw to extract sensitive information, modify records, or perform denial-of-service attacks against the affected system.

Since the attack can be launched remotely by authenticated users with specific permissions, it poses a significant risk to the confidentiality, integrity, and availability of the data.

How can this vulnerability be detected on my network or system? Can you suggest some commands?

This vulnerability exists in the getDataBySQL method of the GoViewDataServiceImpl.java file in the yudao-cloud project, where raw SQL queries are executed without proper validation. Detection involves identifying if the vulnerable endpoint is accessible and if the report:go-view-data:get-by-sql permission is granted to users.

To detect exploitation attempts or presence of this vulnerability, you can monitor network traffic or application logs for suspicious SQL queries or unusual access patterns to the affected endpoint.

• Check for access to the vulnerable endpoint that executes raw SQL queries.
• Look for SQL injection patterns in logs, such as tautologies, UNION statements, or unexpected SQL keywords.
• Use commands like grep or log analysis tools to search application logs for suspicious SQL inputs.
• Example command to search logs for suspicious SQL keywords: grep -iE "(union|select|insert|update|delete|drop|--|#)" /path/to/application/logs/*
• If possible, use network monitoring tools to capture and analyze traffic to the vulnerable service for anomalous SQL payloads.

What immediate steps should I take to mitigate this vulnerability?

Immediate mitigation steps include restricting access to the vulnerable endpoint and limiting permissions to only trusted users.

Since the vulnerability arises from executing raw SQL queries without parameterization, it is recommended to implement parameterized queries or whitelist-based validation of SQL statements.

If a patch or update is not yet available from the vendor, consider removing or disabling the vulnerable endpoint entirely to prevent exploitation.

• Restrict or disable access to the getDataBySQL function or the affected endpoint.
• Limit the report:go-view-data:get-by-sql permission to only trusted and necessary users.
• Implement input validation and parameterized queries in the code to prevent SQL injection.
• Monitor logs and network traffic for exploitation attempts.

How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

The SQL injection vulnerability in YunaiV yudao-cloud allows authenticated users to execute arbitrary SQL commands, potentially leading to unauthorized access, manipulation, or compromise of sensitive data.

Such unauthorized data access and manipulation can result in violations of data protection regulations and standards like GDPR and HIPAA, which require the protection of personal and sensitive information from unauthorized disclosure or alteration.

Therefore, exploitation of this vulnerability could lead to non-compliance with these regulations due to potential data breaches or improper handling of protected data.
