Definition
What is CWE-564?
This vulnerability occurs when an application uses Hibernate to construct dynamic SQL queries with unsanitized user input, allowing an attacker to alter the query's logic or execute unauthorized SQL commands.
Hibernate is a popular Object-Relational Mapping (ORM) framework for Java, designed to simplify database interactions. However, when developers bypass its parameterized query mechanisms and directly concatenate user-controlled data into Hibernate Query Language (HQL) or Criteria API statements, it creates the same injection risks as traditional SQL. Attackers can exploit this by injecting malicious code through form inputs, URLs, or other data channels, potentially leading to data theft, corruption, or full system compromise.
To prevent this, always use Hibernate's parameter binding features, such as named parameters (:param) or positional parameters (?), which ensure input is treated as data, not executable code. Additionally, adopt the principle of least privilege for database accounts, validate and sanitize all input on the server side, and use Hibernate's built-in escaping functions for any dynamic elements. Regular security testing, including automated DAST/SAST scans and manual code reviews focused on query construction patterns, is essential for identifying and remediating these flaws early in the development lifecycle.

How attackers exploit it
Step-by-step attacker path
- 1
Identify a code path that handles untrusted input without validation.
- 2
Craft a payload that exercises the unsafe behavior — injection, traversal, overflow, or logic abuse.
- 3
Deliver the payload through a normal request and observe the application's reaction.
- 4
Iterate until the response leaks data, executes attacker code, or escalates privileges.
Vulnerable code example
Vulnerable Java
The following code excerpt uses Hibernate's HQL syntax to build a dynamic query that's vulnerable to SQL injection.
String street = getStreetFromUser();
Query query = session.createQuery("from Address a where a.street='" + street + "'"); Secure code example
Secure pseudo
// Validate, sanitize, or use a safe API before reaching the sink.
function handleRequest(input) {
const safe = validateAndEscape(input);
return executeWithGuards(safe);
} What changed: the unsafe sink is replaced (or the input is validated/escaped) so the same payload no longer triggers the weakness.
Prevention checklist
How to prevent CWE-564
- Requirements A non-SQL style database which is not subject to this flaw may be chosen.
- Architecture and Design Follow the principle of least privilege when creating user accounts to a SQL database. Users should only have the minimum privileges necessary to use their account. If the requirements of the system indicate that a user can read and modify their own data, then limit their privileges so they cannot read/write others' data.
- Architecture and Design For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
- Implementation Implement SQL strings using prepared statements that bind variables. Prepared statements that do not bind variables can be vulnerable to attack.
- Implementation Use vigorous allowlist style checking on any user input that may be used in a SQL command. Rather than escape meta-characters, it is safest to disallow them entirely. Reason: Later use of data that have been entered in the database may neglect to escape meta-characters before use. Narrowly define the set of safe characters based on the expected value of the parameter in the request.
Detection signals
How to detect CWE-564
Run dynamic application security testing against the live endpoint.
Watch runtime logs for unusual exception traces, malformed input, or authorization bypass attempts.
Code review: flag any new code that handles input from this surface without using the validated framework helpers.

Frequently asked questions
What is CWE-564?
This vulnerability occurs when an application uses Hibernate to construct dynamic SQL queries with unsanitized user input, allowing an attacker to alter the query's logic or execute unauthorized SQL commands.
How serious is CWE-564?
MITRE has not published a likelihood-of-exploit rating for this weakness. Treat it as medium-impact until your threat model proves otherwise.
What languages or platforms are affected by CWE-564?
MITRE lists the following affected platforms: SQL, Database Server.
How can I prevent CWE-564?
A non-SQL style database which is not subject to this flaw may be chosen. Follow the principle of least privilege when creating user accounts to a SQL database. Users should only have the minimum privileges necessary to use their account. If the requirements of the system indicate that a user can read and modify their own data, then limit their privileges so they cannot read/write others' data.
