DBIx::QuickORM SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-13766

DBIx::QuickORM is a Perl library used within application code to handle database interactions. While it can be used in internet-facing web applications to process user input, it is a library rather than a standalone network service or appliance. Its exposure depends entirely on whether a developer uses it to process untrusted input in an application that is reachable from the public internet.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory details a critical vulnerability in a Perl library used for database interactions, allowing attackers to inject malicious SQL code through unquoted identifiers. This could lead to unauthorized data access, modification, or denial of service if the library is used to process untrusted input in internet-facing applications.

SQL injection in database interaction library.
Impacts data security if processing untrusted input.
Confirm relevance and exposure in applications.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending specially crafted input to an application that uses the affected Perl library. This input, when processed by the library's SQL builder, can lead to SQL injection, allowing the attacker to manipulate database queries. The vulnerability could result in unauthorized access, modification, or disclosure of sensitive data.

Unauthenticated network access required.
SQL identifiers in user input.
Data disclosure and tampering.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an attacker to inject malicious SQL code into database queries, potentially leading to unauthorized access, modification, or deletion of sensitive data. This risk exists when the affected software processes unquoted SQL identifiers, such as those used in ordering, filtering, or updating database records, with untrusted input.

Database identifiers and structure.
Malicious input in identifier fields.
Data disclosure and tampering.

Operational Fix

Recommended remediation, mitigation, and detection steps

Applications leveraging DBIx::QuickORM for database interaction are the primary concern. Application owners are responsible for identifying instances of this Perl library, confirming their reachability and business criticality, and then planning remediation. Given the library's function, security teams should also be involved to assess exposure, particularly if the application processes untrusted user input in identifier positions. Coordination with vendor-management may be necessary if the affected application is a third-party product.

Application owners should own the issue.
Verify untrusted input to identifier positions.
Plan remediation based on risk and criticality.

Frequently asked questions

What is DBIx::QuickORM?

DBIx::QuickORM is a Perl library that simplifies database interactions by acting as an Object-Relational Mapper (ORM). Developers use it within their application code to translate database records into objects, making it easier to perform common tasks like querying, updating, and inserting data into a database.

Why is CVE-2026-13766 a security risk?

This CVE involves a vulnerability classified as CWE-89, or SQL Injection. The library fails to properly quote SQL identifiers—such as column names or table aliases—before incorporating them into queries. Because these identifiers are treated as raw text, an attacker can insert malicious SQL code if they can control the input, potentially gaining unauthorized access to or altering the underlying database.

How does an attacker trigger this vulnerability?

The flaw is triggered when an application forwards untrusted user input directly into identifier positions, such as order_by clauses, field lists, or join aliases. It is important to note that this bug does not affect standard data values; those are handled securely via placeholder binding. The vulnerability only exists when the developer enables dynamic, user-controlled SQL structure.

Is my application vulnerable to CVE-2026-13766?

Halo Surface Signal indicates that your exposure depends on whether your application is internet-facing and uses this library to process untrusted input. Because DBIx::QuickORM is a component integrated into your custom code rather than a standalone network service, you must verify if your application passes raw user input into the library's identifier-based configuration options.

Do I need to update my code to fix this?

Yes, you should begin by identifying all instances of DBIx::QuickORM within your applications. The primary fix is to update to version 0.000026 or later, which addresses the identifier handling. If updating is not immediately possible, audit your code to ensure that no untrusted user input is allowed to reach the affected identifier positions in your database queries.
