NVD Description

Note: Versions mentioned in the description apply only to the upstream python-markdown package and not the python-markdown package as distributed by Debian.

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.
