CVE-2021-32859 Information

Description

The Baremetrics date range picker is a solution for selecting both date ranges and single dates from a single calender view. Versions 1.0.14 and prior are prone to cross-site scripting (XSS) when handling untrusted placeholder entries. An attacker who is able to influence the field placeholder when creating a Calendar instance is able to supply arbitrary html or javascript that will be rendered in the context of a user leading to XSS. There are no known patches for this issue.
