CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Loofah >= 2.2.0, < 2.19.1
uses recursion for sanitizing CDATA
sections, making it susceptible to stack exhaustion and raising a SystemStackError
exception. This may lead to a denial of service through CPU resource consumption.
Upgrade to Loofah >= 2.19.1
.
Users who are unable to upgrade may be able to mitigate this vulnerability by limiting the length of the strings that are sanitized.
