CVE-2026-52348 Overview
CVE-2026-52348 is a SQL injection vulnerability in cool-admin-java 8.0.0. The flaw resides in the order() method of CrudOption.java, where attacker-controlled input reaches a SQL statement without proper sanitization. The vulnerability is classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).
Attackers can exploit this issue remotely over the network without authentication or user interaction. Successful exploitation compromises the confidentiality, integrity, and availability of the backing database.
Critical Impact
Unauthenticated remote attackers can inject arbitrary SQL through the order() method, enabling database exfiltration, tampering, and potential lateral movement inside the application backend.
Affected Products
- cool-admin-java version 8.0.0
- The CrudOption.java component containing the vulnerable order() method
- Applications built on the cool-admin-java 8.0.0 framework

Technical Details for CVE-2026-52348
Vulnerability Analysis
The vulnerability exists in the order() method of CrudOption.java within cool-admin-java 8.0.0. This method handles ORDER BY clause construction for CRUD list operations. The framework concatenates client-supplied ordering parameters directly into the resulting SQL statement.
Because ORDER BY values cannot be parameterized through standard prepared statement placeholders, developers frequently interpolate them as raw strings. Without an allow-list of valid column names and sort directions, an attacker can append arbitrary SQL fragments through this path.
The issue is reachable through the CRUD list endpoints exposed by any application built on cool-admin-java 8.0.0. Because the framework provides these endpoints by default, the vulnerable surface exists in any deployment that has not explicitly patched or disabled the affected sort functionality.
Root Cause
The root cause is missing input validation and unsafe string concatenation when building the SQL ORDER BY clause. The order() method trusts the sort field and direction supplied by the client. It does not compare them against a fixed list of permitted columns or the ASC/DESC literals.
Attack Vector
An unauthenticated remote attacker sends a crafted HTTP request to a CRUD list endpoint exposed by a cool-admin-java 8.0.0 application. The attacker places SQL syntax inside the ordering parameter consumed by CrudOption.order(). When the server assembles and executes the query, the injected fragment is treated as SQL. Standard SQL injection techniques such as UNION-based extraction, boolean-based blind inference, and time-based blind inference apply.
No verified public exploit code is available at this time. Technical discussion is tracked in the GitHub Issue Discussion.
Detection Methods for CVE-2026-52348
Indicators of Compromise
- HTTP requests to CRUD list endpoints containing SQL keywords such as UNION, SELECT, SLEEP, BENCHMARK, or comment tokens (--, /*) in ordering parameters
- Database logs showing malformed or unusually complex ORDER BY clauses referencing tables outside the requesting entity
- Application error logs referencing CrudOption.order() with SQL syntax exceptions
- Sudden spikes in query latency correlated with time-based blind injection payloads
Detection Strategies
- Deploy web application firewall rules that inspect sort and order query parameters for SQL metacharacters and reject non allow-listed values
- Enable database query auditing and alert on ORDER BY clauses that contain subqueries, function calls, or sleep primitives
- Correlate application stack traces referencing CrudOption.java with the originating HTTP request to identify probing activity
Monitoring Recommendations
- Monitor authentication-free CRUD endpoints for high-volume parameter fuzzing patterns
- Track outbound database query rates and unusual result set sizes indicative of data exfiltration
- Instrument the application with runtime application self-protection (RASP) or logging around the order() method to capture raw parameter values
How to Mitigate CVE-2026-52348
Immediate Actions Required
- Inventory all deployments running cool-admin-java 8.0.0 and identify externally reachable CRUD endpoints
- Restrict access to administrative and CRUD list endpoints behind authentication and network controls until a fix is applied
- Apply upstream patches or code-level fixes to the order() method in CrudOption.java that enforce an allow-list of column names and sort directions
- Rotate database credentials and audit database contents if exploitation is suspected
Patch Information
No official patched version has been documented in the NVD entry at the time of publication. Track remediation status through the GitHub Issue Discussion for the cool-admin-java project.
Workarounds
- Implement a server-side allow-list that validates ordering parameters against known column names and rejects any value outside ASC or DESC
- Place a web application firewall in front of the application to filter SQL metacharacters in sort-related parameters
- Apply the database principle of least privilege so the application account cannot read tables or execute functions beyond its operational scope
- Disable or remove unused CRUD list endpoints exposed by the framework
# Example allow-list validation pattern for sort parameters
# Reject any request whose sort field or direction is not in the allow-list
ALLOWED_SORT_FIELDS="id name createTime updateTime"
ALLOWED_SORT_DIRS="ASC DESC"
