Name of the Vulnerable Software and Affected Versions markdown-to-jsx versions prior to 7.4.0

Description The issue is related to Cross-site Scripting (XSS) via the src property due to improper input sanitization. An attacker can execute arbitrary code by injecting a malicious iframe element in the markdown.

Recommendations For versions prior to 7.4.0, update to version 7.4.0 or later to resolve the issue. As a temporary workaround, consider disabling the use of the src property in markdown until a patch is available. Restrict access to markdown elements to minimize the risk of exploitation. Avoid using the src property in markdown until the issue is resolved.
