## Overview

Sonatype Nexus Repository 3 did not properly filter internal configuration keys from user-supplied task properties when creating or updating a scheduled task through the administrative UI. An account holding permission to create at least one scheduled task type could supply a crafted property value that caused the system to overwrite the configuration of an unrelated, existing task instead of creating a new one.

## Affected

- `nexus_repository_manager >= 3.91.0, < 3.95.0`

## Remediation

Upgrade past the affected range:

- `nexus_repository_manager 3.95.0`
