# MQR mode

## Overview <a href="#overview" id="overview"></a>

MQR Mode aims to more accurately represent the impact an issue has on all [software-qualities](https://docs.sonarsource.com/sonarqube-server/2025.4/user-guide/rules/software-qualities "mention"). It does this by assigning a separate severity to a rule for each software quality it might impact. This approach focuses on ensuring the impact on all software qualities is clear, not just the one most severely impacted.

<table><thead><tr><th width="101">Severity</th><th>Definition</th></tr></thead><tbody><tr><td>Blocker</td><td>An issue that has a significant probability of severe unintended consequences on the application that should be fixed immediately. This includes bugs leading to production crashes and security flaws allowing attackers to extract sensitive data or execute malicious code.</td></tr><tr><td>High</td><td>An issue with a high impact on the application that should be fixed as soon as possible.</td></tr><tr><td>Medium</td><td>An issue with a medium impact.</td></tr><tr><td>Low</td><td>An issue with a low impact.</td></tr><tr><td>Info</td><td>There is no expected impact on the application. For informational purposes only.</td></tr></tbody></table>
