    CVE-2018-5773

    Published: 18 Jan 2018Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
