Original description The description as published by the source.
A stored cross-site scripting (XSS) vulnerability in Bynder v0.1.394 allows attackers to execute arbitrary web scripts or HTML via a crafted payload. NOTE: this is disputed by the Supplier because v0.1.394 was never a valid version number, and because there is no available information on what v0.1.394 system or environment may have been used for this XSS finding.
