CVE-2026-8724: Dataease SQL Injection Vulnerability

CVE-2026-8724 Overview

CVE-2026-8724 is a SQL injection vulnerability in DataEase 2.10.20, an open-source data visualization and business intelligence platform. The flaw resides in the SqlparserUtils.transFilter function within SqlparserUtils.java, part of the Data Dashboard component. Attackers with high privileges can manipulate filter input to inject arbitrary SQL statements remotely over the network. The exploit has been publicly released, increasing the risk of opportunistic attacks against exposed DataEase deployments. The vulnerability is classified under [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements).

Critical Impact

Authenticated attackers can inject SQL through the Data Dashboard filter functionality, exposing or modifying backend database content on DataEase 2.10.20 instances.

Affected Products

• DataEase 2.10.20
• Component: Data Dashboard
• Vulnerable file: SqlparserUtils.java (transFilter function)

Technical Details for CVE-2026-8724

Vulnerability Analysis

The vulnerability exists in the transFilter method of SqlparserUtils.java, which processes filter parameters used by the Data Dashboard before passing them into SQL query construction. The method fails to properly neutralize special SQL syntax elements supplied through filter variables. An authenticated attacker can craft filter values that break out of the intended query context and append arbitrary SQL clauses. Because the attack is delivered over the network through authenticated dashboard interactions, no local access or user interaction is required.

Successful exploitation can lead to unauthorized read or modification of database content accessible to the DataEase backend. The privilege requirement limits opportunistic exploitation, but the public availability of proof-of-concept material lowers the bar for insiders or attackers who have already compromised dashboard credentials.

Root Cause

The root cause is improper neutralization of user-supplied input passed into SQL statements built by SqlparserUtils.transFilter. Filter variables flow into dynamic SQL construction without parameterized queries or strict input validation, satisfying the conditions for both [CWE-89] and [CWE-74].

Attack Vector

Exploitation occurs over the network against the DataEase web interface. An authenticated user invokes a Data Dashboard endpoint that calls transFilter with attacker-controlled filter values containing SQL syntax. The injected SQL executes within the backend database session associated with DataEase, potentially exposing schema information, stored data, or enabling data modification depending on database permissions.

No verified proof-of-concept code is published in the provided references. Technical details and a write-up are available through the GitHub PoC Repository and VulDB #364315.

Detection Methods for CVE-2026-8724

Indicators of Compromise

• Unexpected SQL syntax tokens such as UNION, --, /*, or OR 1=1 appearing in DataEase dashboard filter request parameters.
• Backend database errors or anomalous query durations originating from the DataEase application user.
• Authenticated dashboard requests from accounts accessing filter endpoints outside their normal usage pattern.

Detection Strategies

• Inspect DataEase application logs for filter parameters containing SQL metacharacters or stacked statements targeting transFilter invocations.
• Enable database audit logging to capture queries originating from the DataEase service account and flag those containing injected clauses.
• Deploy a web application firewall rule set tuned for SQL injection patterns on URIs handling dashboard filters.

Monitoring Recommendations

• Monitor authenticated DataEase sessions for high-volume or malformed filter submissions indicative of automated exploitation.
• Alert on database error spikes, large result-set transfers, or schema enumeration queries from the DataEase backend user.
• Correlate dashboard filter activity with sudden privilege use or access to sensitive tables not normally referenced by dashboards.

How to Mitigate CVE-2026-8724

Immediate Actions Required

• Restrict access to the DataEase Data Dashboard to trusted, authenticated users and remove unnecessary high-privilege accounts.
• Place DataEase 2.10.20 instances behind a reverse proxy or WAF configured to block common SQL injection payloads.
• Rotate credentials for the DataEase database account and enforce least-privilege permissions on its database role.

Patch Information

No vendor patch is identified in the provided references at the time of publication. Monitor the DataEase project advisory and VulDB #364315 for an official fix. Upgrade as soon as a corrected release addressing SqlparserUtils.transFilter becomes available.

Workarounds

• Limit network exposure of DataEase 2.10.20 by restricting it to internal networks or VPN-only access until a patch is released.
• Reduce privileges of the DataEase database user to read-only on non-essential schemas to limit injection impact.
• Disable or restrict use of Data Dashboard features that invoke filter variables for accounts that do not require them.
