CVE-2026-63154 in Agora Project
Summary
by MITRE • 10/13/2026
Omnispace Agora Project before 26.10.0 contains a SQL identifier injection vulnerability that allows a space administrator to escalate privileges by supplying caller-controlled agoraFields[] names as unvalidated SQL column identifiers during the user import flow. Attackers can inject privileged column names such as generalAdmin or use backtick-injection techniques to set administrative flags and escalate to general administrator privileges.

The Omnispace Agora Project, prior to version 26.10.0, contains a critical SQL identifier injection vulnerability within its user import functionality. This flaw arises from the improper handling of caller-controlled input specifically in the agoraFields[] array during the process of importing users into the system. Unlike standard SQL injection which targets data values, this vulnerability exploits the structural components of the SQL query itself by allowing an attacker to inject arbitrary identifiers such as column names or table aliases directly into the database command structure. The root cause lies in the application's failure to validate or sanitize these field names before incorporating them into dynamic SQL statements used for user creation and configuration updates.
In a typical secure implementation, any input that influences the schema of a query must be strictly validated against an allowlist of known safe identifiers. In this vulnerable scenario, however, the system accepts arbitrary strings provided by the space administrator via the agoraFields[] parameter without sufficient verification. This lack of validation permits an attacker to manipulate the SQL statement's structure rather than just its data payload. By injecting privileged column names such as generalAdmin or utilizing backtick-injection techniques common in MySQL environments, the attacker can force the database engine to interpret these injected strings as legitimate schema elements within the INSERT or UPDATE operations associated with user import flows.
The operational impact of this vulnerability is severe due to the potential for privilege escalation. An authenticated space administrator, who may have limited privileges under normal circumstances, can exploit this flaw to modify administrative flags that are typically reserved for higher-level roles. By injecting a privileged column name into the query structure and supplying corresponding values through other parameters or by leveraging default behaviors in the database layer, the attacker can effectively grant themselves general administrator privileges. This bypasses standard access control mechanisms because the vulnerability operates at the data manipulation level rather than the authentication or authorization logic level, allowing unauthorized elevation of rights without needing to compromise existing credentials further.
From a classification perspective, this issue aligns with CWE-94 Improper Control of Generation of Code SQL Identifier Injection and falls under MITRE ATT&CK technique T1059 Command and Scripting Interpreter if the injection leads to broader command execution, though primarily it represents an authorization bypass via data manipulation (T1078 Valid Accounts). The vulnerability highlights a common misconception that input validation is only necessary for string values; in reality, identifiers such as table names, column names, and sort orders must also be rigorously validated.
To mitigate this risk, immediate patching to version 26.10.0 or later is required where the issue has been addressed by implementing strict allowlisting of permitted field names during the user import process. Development teams should ensure that all dynamic SQL components are constructed using parameterized queries for data values and hardcoded identifiers for schema elements whenever possible. If dynamic identifiers are unavoidable, they must be validated against a predefined list of acceptable column names before being concatenated into SQL statements. Additionally, implementing principle of least privilege ensures that even if such vulnerabilities exist in other parts of the application, the impact is contained by restricting what actions authenticated users can perform through standard interfaces.
