CVE-2026-14363

Description

A flaw was found in the Mediawiki Cargo Extension. This vulnerability, identified as SQL Injection, allows an attacker to execute malicious SQL commands. By exploiting improper handling of special characters in SQL commands, an attacker can potentially access, modify, or delete sensitive data within the database, leading to unauthorized information disclosure or data manipulation.

Statement

An Important SQL injection flaw affects the Mediawiki Cargo Extension, enabling unauthenticated attackers to execute arbitrary SQL commands. This can lead to unauthorized access, modification, or deletion of sensitive database information. The impact is significant in deployments where Mediawiki instances are exposed to untrusted networks and the Cargo Extension is actively utilized.

Mitigation

To mitigate the risk, restrict network access to the Mediawiki instance to only trusted users and networks. This can be achieved by configuring firewall rules to limit inbound connections to the server hosting Mediawiki. If the Mediawiki Cargo Extension is not essential for your deployment, consider disabling or removing it, following Mediawiki's official documentation for extension management.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Confidentiality,Integrity,Availability

Technical Impact: Execute Unauthorized Code or Commands

Adversaries could execute system commands, typically by changing the SQL statement to redirect output to a file that can then be executed.

Confidentiality

Technical Impact: Read Application Data

Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL injection vulnerabilities.

Authentication

Technical Impact: Gain Privileges or Assume Identity; Bypass Protection Mechanism

If poor SQL commands are used to check user names and passwords or perform other kinds of authentication, it may be possible to connect to the product as another user with no previous knowledge of the password.

Access Control

Technical Impact: Bypass Protection Mechanism

If authorization information is held in a SQL database, it may be possible to change this information through the successful exploitation of a SQL injection vulnerability.

Integrity

Technical Impact: Modify Application Data

Just as it may be possible to read sensitive information, it is also possible to modify or even delete this information with a SQL injection attack.
