Package : ruby-redcarpet
CVE ID : CVE-2020-26298
Debian Bug : 980057

Johan Smits discovered that ruby-redcarpet, a markdown parser, did not
properly validate its input. This would allow an attacker to mount a
cross-site scripting attack.

For the stable distribution (buster), this problem has been fixed in
version 3.4.0-4+deb10u1.

We recommend that you upgrade your ruby-redcarpet packages.
