SCA: security update for remark-html (GHSA-9q5w-79cv-947m)
medium Tenable Self-Hosted Container Security Plugin ID 413412
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- remark-html is an open source nodejs library which compiles Markdown to HTML. In affected versions the
documentation of remark-html has mentioned that it was safe by default. In practice the default was never
safe and had to be opted into. That is, user input was not sanitized. This means arbitrary HTML can be
passed through leading to potential XSS attacks. The problem has been patched in 13.0.2 and 14.0.1:
`remark-html` is now safe by default, and the implementation matches the documentation. On older affected
versions, pass `sanitize: true` if you cannot update. (CVE-2021-39199)
