Security Advisories 🚨

🚨 REXML ReDoS vulnerability

Impact

The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;).

This does not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. Note that Ruby 3.1 will reach EOL on 2025-03.

Patches

The REXML gem 3.3.9 or later include the patch to fix the vulnerability.

Workarounds

Use Ruby 3.2 or later instead of Ruby 3.1.
