CVE-2026-78182 Overview
CVE-2026-78182 is a SQL injection vulnerability affecting Shenzhen Gongji Technology XBROTHER Dynamic Environment Monitoring System versions up to 300R004C00B300. The flaw resides in the PlanController.getImmediatePlans function within the /xbreport/api/v1/plamange/plansImmediate endpoint. Attackers can manipulate the order or sort request arguments to inject arbitrary SQL statements. Exploitation occurs remotely over the network without authentication or user interaction. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed monitoring systems.
Critical Impact
Unauthenticated remote attackers can inject SQL into the plansImmediate API endpoint, potentially exposing or modifying database contents of the environmental monitoring platform.
Affected Products

Technical Details for CVE-2026-78182
Vulnerability Analysis
The vulnerability is a SQL injection flaw classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The PlanController.getImmediatePlans method processes user-supplied order and sort parameters and concatenates them directly into a backend SQL query. Because these parameters flow into the query without sanitization or parameterization, an attacker can break out of the intended query context and append arbitrary SQL clauses.
A remote attacker requires no credentials to reach the /xbreport/api/v1/plamange/plansImmediate endpoint. Successful exploitation can lead to unauthorized read or modification of database records containing environmental telemetry, plan configurations, and potentially operator credentials.
Root Cause
The root cause is the use of dynamic SQL construction with untrusted input. Sorting parameters such as order and sort are typically appended to ORDER BY clauses, where prepared statements cannot bind identifiers. Without an allowlist of valid column names or sort directions, the application executes attacker-controlled SQL fragments verbatim.
Attack Vector
Exploitation is performed over the network by issuing a crafted HTTP request to the vulnerable API endpoint. The attacker manipulates the order or sort query parameters with SQL payloads such as time-based, boolean-based, or UNION-based injection strings. No authentication or user interaction is required. Public disclosure of the technique lowers the barrier for automated scanning and mass exploitation. Full technical details are available in the VulDB entry for CVE-2026-78182 and the supplementary Feishu writeup.
Detection Methods for CVE-2026-78182
Indicators of Compromise
- HTTP requests to /xbreport/api/v1/plamange/plansImmediate containing SQL metacharacters such as single quotes, UNION, SELECT, SLEEP(, or -- in the order or sort parameters.
- Unusual database query latency or errors originating from the XBROTHER application backend.
- Web server logs showing large response payloads from the plansImmediate endpoint following abnormal query strings.
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the order and sort parameters on the plansImmediate endpoint for SQL injection signatures.
- Correlate database audit logs with application access logs to identify queries containing injected clauses tied to sort parameters.
- Monitor for repeated requests from a single source enumerating the endpoint with varying payloads, indicating automated exploitation attempts.
Monitoring Recommendations
- Enable verbose logging on the XBROTHER application server and forward logs to a centralized SIEM for correlation.
- Alert on database error responses (HTTP 500) returned by /xbreport/api/v1/plamange/* endpoints.
- Track outbound network connections from the monitoring host that deviate from baseline behavior, which may indicate post-exploitation data staging.
How to Mitigate CVE-2026-78182
Immediate Actions Required
- Restrict network access to the XBROTHER management interface using firewall rules or VPN-only access until a vendor patch is available.
- Deploy WAF signatures that block SQL injection payloads targeting the order and sort parameters on /xbreport/api/v1/plamange/plansImmediate.
- Review database and application logs for prior exploitation attempts using the indicators listed above.
- Rotate database credentials used by the XBROTHER application if evidence of exploitation is found.
Patch Information
At the time of publication, no vendor advisory or patched version has been referenced in the NVD entry for CVE-2026-78182. Administrators should monitor Shenzhen Gongji Technology communications and the VulDB vulnerability overview for updates on remediated builds beyond 300R004C00B300.
Workarounds
- Place the XBROTHER Dynamic Environment Monitoring System behind an authenticated reverse proxy that validates request parameters against an allowlist.
- Implement input validation at the network layer to reject order and sort values that are not simple alphanumeric column names.
- Disable or firewall the /xbreport/api/v1/plamange/plansImmediate endpoint if it is not required for operations.
- Segment the monitoring system from sensitive OT and IT networks to limit lateral movement in the event of database compromise.
