CVE-2022-23517: Debian Linux

High severity, CVSS 7.5. EPSS: 1.5% chance of exploitation in the next 30 days.

rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. 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. This issue has been patched in version 1.4.4.

Affected products

• Debian Debian Linux: version 10.0 only
• Rubyonrails Rails Html Sanitizers: before 1.4.4 (fixed in 1.4.4)
