發布日:2018/7/12修改日:2024/9/30
描述
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.
