ElectricSQL /v1/shape API SQL Injection Vulnerability

hello@craftedsignal.io — Wed, 22 Apr 2026 12:00:00 +0000

Electric, a Postgres sync engine, is vulnerable to SQL injection in the order_by parameter of the ElectricSQL /v1/shape API endpoint. This vulnerability exists in versions 1.1.12 to before 1.5.0. Exploitation allows any authenticated user to execute arbitrary SQL queries, leading to potential data breaches, data manipulation, and complete database compromise. Successful exploitation can result in unauthorized access to sensitive information, modification of critical data, and denial of service. Organizations using vulnerable versions of ElectricSQL are at high risk. The vulnerability is resolved in version 1.5.0.

Attack Chain

An attacker authenticates to the ElectricSQL application.
The attacker crafts a malicious HTTP request targeting the /v1/shape API endpoint.
The crafted request includes a SQL injection payload within the order_by parameter.
The ElectricSQL application processes the request without proper sanitization of the order_by parameter.
The malicious SQL payload is executed against the underlying PostgreSQL database.
The attacker leverages the SQL injection vulnerability to extract sensitive data, such as user credentials or proprietary information, using SELECT statements.
The attacker escalates privileges by manipulating database objects or creating new administrative accounts using CREATE and ALTER statements.
The attacker destroys data or renders the database unavailable using DELETE and DROP statements, achieving complete system compromise.

Impact

Successful exploitation of this SQL injection vulnerability could lead to a complete compromise of the underlying PostgreSQL database. This may result in unauthorized access to sensitive data, including customer information, financial records, and intellectual property. Attackers could also modify or delete data, leading to data loss, service disruption, and reputational damage. Given the potential for complete data destruction, organizations are urged to remediate this vulnerability immediately.

Recommendation

Upgrade ElectricSQL to version 1.5.0 or later to patch the vulnerability (CVE-2026-40906).
Implement input validation and sanitization for all user-supplied data, especially in the order_by parameter of the /v1/shape API.
Monitor web server logs for suspicious activity, such as unusual characters or SQL keywords in the order_by parameter of requests to the /v1/shape API to enable the “Detect Suspicious SQL Injection Attempt in ElectricSQL API Request” rule.
Deploy the Sigma rule “Detect Suspicious SQL Injection Error Messages” to identify potential exploitation attempts based on error responses from the database server.

PostgreSQL JDBC Driver SQL Injection Vulnerability

hello@craftedsignal.io — Tue, 24 Mar 2026 10:21:21 +0000

A vulnerability exists within the PostgreSQL JDBC Driver that allows for SQL injection attacks. The specifics of the vulnerable versions are not provided, however, exploitation allows a remote, unauthenticated attacker to inject arbitrary SQL commands into the application’s database queries. This can lead to data exfiltration, modification, or even complete database compromise. The lack of specific version information makes targeted patching difficult, emphasizing the need for broad detection and prevention strategies. Successful exploitation can have severe consequences for applications relying on the vulnerable JDBC driver, impacting data confidentiality, integrity, and availability.

Attack Chain

The attacker identifies an application using a vulnerable version of the PostgreSQL JDBC driver.
The attacker crafts a malicious SQL injection payload designed to exploit the vulnerability.
The attacker injects the payload through a user-supplied input field, such as a form or API endpoint.
The application, using the vulnerable JDBC driver, constructs an SQL query incorporating the attacker’s payload.
The injected SQL code is executed by the PostgreSQL database server.
The attacker gains unauthorized access to sensitive data within the database.
The attacker may modify or delete data, potentially causing application malfunction or data loss.
The attacker could potentially use the SQL injection to execute operating system commands on the database server if the database user has sufficient privileges.

Impact

Successful exploitation of this SQL injection vulnerability can lead to complete compromise of the application database. This can result in the exfiltration of sensitive data (credentials, PII, financial records), unauthorized data modification or deletion, and potential disruption of application services. The number of potential victims is vast, as many applications use the PostgreSQL JDBC driver to connect to PostgreSQL databases. The impact ranges from data breaches and financial loss to reputational damage and legal liabilities.

Recommendation

Implement parameterized queries or prepared statements in application code to prevent SQL injection (reference secure coding practices).
Deploy the provided Sigma rules to detect suspicious SQL queries indicative of injection attempts (Sigma rules below).
Monitor web server logs for unusual patterns or error messages related to database interactions (webserver log source).
Regularly update the PostgreSQL JDBC driver to the latest version from a trusted source after vendor confirms fix.
