REXML is an XML toolkit for Ruby.The REXML gem before 3.2.6 has a denial of service vulnerability when it parses an XML that has many ``s in an attribute value.Those who need to parse untrusted XMLs may be impacted to this vulnerability.The REXML gem 3.2.7 or later include the patch to fix this vulnerability.As a workaround, don't parse untrusted XMLs.(CVE-2024-35176)

Tenable has extracted the preceding description block directly from the EulerOS ruby security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
