Description

An issue was discovered in markdown2 (aka python-markdown2) through 2.3.5. The safe_mode feature which is supposed to sanitize user input against XSS is flawed and does not escape the input properly. With a crafted payload XSS can be triggered as demonstrated by omitting the final ’’ character from an IMG tag.
