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. Se ha descubierto un problema en markdown2 (también conocido como python-markdown2) hasta la versión 2.3.5. La característica safe_mode, que se supone que sanear entradas contra XSS, tiene errores y no escapa las entradas correctamente. • https://github.com/trentm/python-markdown2/issues/285 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
