Debian LTS Advisory DLA-2526-1 [email protected]

Package : ruby-redcarpet
Version : 3.3.4-2+deb9u1
CVE ID : CVE-2020-26298
Debian Bug : 980057

In Redcarpet before version 3.5.1, there is an injection
vulnerability which can enable a cross-site scripting attack.

In affected versions, no HTML escaping was being performed when
processing quotes. This applies even when the :escape_html
option was being used.

For Debian 9 stretch, this problem has been fixed in version
3.3.4-2+deb9u1.

We recommend that you upgrade your ruby-redcarpet packages.

For the detailed security status of ruby-redcarpet please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/ruby-redcarpet
