CVE-2018-3741  (opens in a new tab)
CWE-79  (opens in a new tab)

How to fix?

Upgrade RHEL:7 rubygems to version 0:2.6.14.3-90.el7cf or higher.
This issue was patched in RHSA-2019:0212.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygems package and not the rubygems package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

There is a possible XSS vulnerability in all rails-html-sanitizer gem versions below 1.0.4 for Ruby. The gem allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments, and these attributes can lead to an XSS attack on target applications. This issue is similar to CVE-2018-8048 in Loofah. All users running an affected release should either upgrade or use one of the workarounds immediately.
