Name of the Vulnerable Software and Affected Versions Loofah versions prior to 2.19.1

Description Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. It contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to sanitize certain SVG attributes. This may lead to a denial of service through CPU resource consumption.

Recommendations Upgrade to Loofah version 2.19.1 or later. As a temporary workaround, consider restricting the use of Loofah for sanitizing SVG attributes until a patch is applied.
