CVE-2026-63224 in OpenRemote
Summary
by MITRE • 10/31/2026
OpenRemote is an open-source internet-of-things platform. Prior to 1.26.0, the `datapoint export` API constructs `CSV crosstab` SQL by concatenating an `asset name` and `attribute name` into a `COPY` query that uses `crosstab` and streams `TO STDOUT`. The `asset name` enters both a double-quoted column identifier and a category query enclosed by the fixed `$cat$` delimiter. Escaping single quotes in one string context does not escape embedded double quotes in identifiers or protect that dollar-quote boundary. An authenticated user permitted to create or rename an asset and read/export datapoints for one of its attributes can store SQL metacharacters in the name and request a `crosstab` export, causing injected SELECT output to be returned in the normal ZIP/CSV response. This enables database exfiltration without direct database or filesystem access or token forgery. In a multi-tenant deployment it can expose other tenants' data if the manager's database role can read shared tables; integrity and availability effects are not established by the demonstrated read primitive. This issue is fixed in version 1.26.0.

OpenRemote, an open-source internet-of-things platform, contains a critical SQL injection vulnerability within its datapoint export functionality prior to version 1.26.0. The flaw resides in the API endpoint responsible for exporting data as CSV crosstab reports. When this feature is invoked, the backend constructs a PostgreSQL COPY query that utilizes the tablefunc extension's crosstab function to format and stream results directly to standard output. This process involves concatenating user-supplied input, specifically asset names and attribute names, into SQL identifiers and category delimiters without adequate sanitization or parameterized query usage. The architecture relies on embedding these inputs within double-quoted strings for column identifiers and dollar-quoted strings delimited by $cat$ tags for category queries.
The technical root cause is a failure to properly escape special characters across different string contexts. While the application may attempt to escape single quotes in certain parts of the query, it fails to handle embedded double quotes required for SQL identifiers or protect the boundaries of the dollar-quoted strings. This inconsistency allows an authenticated user with permissions to create or rename assets and export datapoints to inject arbitrary SQL metacharacters into these fields. By carefully crafting asset names containing characters such as double quotes or dollar signs, a malicious actor can break out of the intended string context. Once the injection point is reached within the crosstab query structure, the attacker can manipulate the SELECT statement that generates the output data.
The operational impact of this vulnerability is severe, primarily enabling unauthorized database exfiltration. Because the injected SQL code executes as part of a legitimate export operation, the results are returned in the normal ZIP or CSV response stream sent to the client. This mechanism allows an attacker to read arbitrary data from the underlying PostgreSQL database without needing direct access to the database server, filesystem privileges, or token forgery capabilities. In multi-tenant deployments where shared tables exist and the application's database role has broad read permissions across tenants, this vulnerability can lead to a complete breach of confidentiality for other users' data. The attacker effectively bypasses logical access controls by exploiting the trusted export feature to dump sensitive information directly into their client-side response files.
From a classification perspective, this issue aligns with CWE-89 Improper Neutralization of Special Elements used in an SQL Command and is categorized under ATT&CK technique T1005 Data from Local System Retrieval via Application Programming Interface or similar data exfiltration vectors depending on the specific execution context within the application layer. The vulnerability represents a classic case of second-order injection where user input stored during asset creation is later processed unsafely during report generation.
To mitigate this risk, organizations running OpenRemote versions prior to 1.26.0 must upgrade immediately to version 1.26.0 or later, which addresses the improper handling of special characters in export queries. For environments where upgrading is not immediately feasible, administrators should restrict database user permissions used by the application to follow the principle of least privilege, ensuring that the service account cannot read tables belonging to other tenants if multi-tenancy is implemented via shared schemas. Additionally, input validation on asset names and attribute names can be strengthened to reject or strictly encode characters such as double quotes, dollar signs, and semicolons before they are ever stored in the database, thereby preventing the payload from being constructed in the first place.
