## Affected

- Unknown Project Management, Bug and Issue Tracking Plugin: fixed in 5.1.0

## Description

The Project Management, Bug and Issue Tracking Plugin WordPress plugin before 5.1.0 does not sanitise and escape user supplied input before using it in a SQL query, allowing unauthenticated attackers to perform SQL injection attacks. This is exploitable in the Project Management, Bug and Issue Tracking Plugin WordPress plugin before 5.1.0's standard front-end issue-tracker configuration.
