Cross site scripting in markdown-to-jsx
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | markdown-to-jsx | < 7.4.0 | 7.4.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
Versions of the package markdown-to-jsx before 7.4.0 are vulnerable 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.
