| Package | Affected versions | Patched versions |
|---|---|---|
| markdown2 | < 2.3.9 | 2.3.9 |
| python-markdown2 | ≤ 2.3.8 |
python-markdown2 through 2.3.8 allows XSS because element names are mishandled unless a \w+ match succeeds. For example, an attack might use elementname@ or elementname- with an onclick attribute.
