0.0%
EPSS Percentile
0th
DjangoBlog 2.0.0.0 through 2.1.0.0 contains a stored cross-site scripting vulnerability because the class_filter comment sanitizer passes event-handler attributes on span, div, pre and code tags. Authenticated commenters can post a div with autofocus and onfocus attributes, executing script without interaction for every visitor, including administrators.
