Atlassian · Gantt-Chart For Jira · CVE-2020-15943
**Name of the Vulnerable Software and Affected Versions**
Gantt-Chart for Jira versions prior to 5.5.4
**Description**
An issue in the Gantt-Chart module allows authenticated attackers to read and write to the module configuration of other users due to a missing privilege check. This can also be used to deliver an XSS payload to other users' dashboards.
**Recommendations**
For versions prior to 5.5.4, update to version 5.5.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the Gantt-Chart module to minimize the risk of exploitation.
