CVE-2026-18912 Overview
CVE-2026-18912 is an authenticated SQL injection vulnerability [CWE-89] in ManageEngine DataSecurity Plus versions prior to 6310. The flaw resides in the Reports module and allows an authenticated technician to execute arbitrary SQL queries against the backing database. Because the scope changes at exploitation (S:C), a successful attacker can reach data outside the vulnerable component's authorization boundary. The vulnerability affects confidentiality only, with no direct integrity or availability impact according to the published CVSS vector.
Critical Impact
An authenticated technician can extract sensitive data classified and monitored by DataSecurity Plus, including audited file activity, user metadata, and compliance records.
Affected Products
- ManageEngine DataSecurity Plus versions before build 6310
- Reports module component within DataSecurity Plus
- Deployments exposing the technician role to internal or partner users

Technical Details for CVE-2026-18912
Vulnerability Analysis
The vulnerability affects the Reports module of ManageEngine DataSecurity Plus, a data visibility and compliance product used to audit file server activity. An authenticated user holding the technician role can inject arbitrary SQL statements through parameters processed by the reporting subsystem. The scope-changed rating indicates the injected queries execute against database contents beyond the technician's intended access scope, exposing records the role should not be able to read directly. Refer to the ManageEngine CVE-2026-18912 Analysis for vendor-supplied technical detail.
Root Cause
The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. Input supplied to the Reports module is concatenated into database queries without parameterized binding or strict allow-list validation. The technician role has legitimate access to the reporting interface, but the underlying query construction does not enforce authorization boundaries on the resulting SQL.
Attack Vector
Exploitation requires network reachability to the DataSecurity Plus web interface and valid technician credentials. No user interaction is required beyond the attacker's own authenticated session. An attacker submits crafted parameters to the Reports module endpoint, causing the server to execute attacker-controlled SQL. This yields the ability to read arbitrary tables in the DataSecurity Plus database, which stores audit trails and monitored file metadata. The EPSS probability at publication was 1.5% (73rd percentile).
No verified public proof-of-concept code is available at the time of publication. Technical detail is limited to the vendor advisory.
Detection Methods for CVE-2026-18912
Indicators of Compromise
- Reports module HTTP requests containing SQL meta-characters such as ', --, UNION, SELECT, or information_schema in parameter values
- Database query logs showing SELECT statements originating from the Reports module against tables unrelated to reporting
- Technician-role sessions generating an atypical volume of report generation requests
- Outbound data transfers immediately following report exports by non-privileged technician accounts
Detection Strategies
- Enable database query logging on the DataSecurity Plus backend and alert on queries containing stacked statements or references to system catalogs
- Deploy web application firewall rules that inspect Reports module parameters for SQL injection payloads
- Baseline normal technician activity and flag deviations in query volume, response size, or endpoint diversity
Monitoring Recommendations
- Forward DataSecurity Plus web server access logs and database audit logs to a centralized analytics platform for correlation
- Monitor for authentication of technician accounts from unexpected source addresses or outside business hours
- Track report export sizes and alert when a single session downloads records exceeding baseline thresholds
How to Mitigate CVE-2026-18912
Immediate Actions Required
- Upgrade ManageEngine DataSecurity Plus to build 6310 or later as published in the vendor advisory
- Audit all accounts assigned the technician role and revoke access for users who do not require it
- Rotate database service account credentials used by DataSecurity Plus after patching
- Review Reports module access logs for the period preceding the patch for signs of exploitation
Patch Information
ManageEngine addressed CVE-2026-18912 in DataSecurity Plus build 6310. Administrators should consult the ManageEngine CVE-2026-18912 Analysis for the download package and upgrade procedure. Apply the update in a maintenance window and verify service health afterward.
Workarounds
- Restrict access to the DataSecurity Plus web console to management VLANs or a VPN until the patch is applied
- Temporarily reduce the number of accounts holding the technician role to trusted administrators only
- Enforce multi-factor authentication on all DataSecurity Plus accounts to raise the cost of credential abuse
- Deploy WAF signatures that block SQL injection patterns on paths associated with the Reports module
# Example WAF rule concept blocking SQL meta-characters on the Reports endpoint
# Adapt to your WAF syntax; test in detection mode before enforcing
