Description

EspoCRM before 10.0.6 contains a stored HTML injection vulnerability that allows unauthenticated attackers to inject HTML by submitting crafted Lead Capture public form data. The request body is stored in LeadCaptureLogRecord.data and rendered unescaped when administrators view the log record, though Content Security Policy blocks JavaScript execution.
