CVE-2021-20829

Name of the Vulnerable Software and Affected Versions: GROWI versions v4.2.19 and earlier

Description: The issue is due to inadequate tag sanitization, allowing remote attackers to execute an arbitrary script on the web browser of the user who accesses a specially crafted page. This enables the execution of arbitrary scripts, potentially leading to unauthorized actions.

Recommendations: For GROWI versions v4.2.19 and earlier, update to a version later than v4.2.19 to resolve the issue. As a temporary workaround, consider implementing additional tag sanitization measures to minimize the risk of exploitation.
