Summary
Inefficient Regular Expression Complexity in rails-html-sanitizer
Details
Summary
Certain configurations of rails-html-sanitizer < 1.4.4
use 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.
Mitigation
Upgrade to rails-html-sanitizer >= 1.4.4
.
Severity
The maintainers have evaluated this as High Severity 7.5 (CVSS3.1).
