Impact The REXML gems from 3.3.3 to 3.4.1 have a DoS vulnerability when parsing XML containing multiple XML declarations. If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities. Patches REXML gems 3.4.2 or later include the patches to fix these vulnerabilities. Workarounds Don't parse untrusted XMLs. References https://www.ruby-lang.org/en/news/2025/09/18/dos-rexml-cve-2025-58767/ : An announcement on www.ruby-lang.org
Recommended action: Upgrade to 3.4.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
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.

Impact The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. Patches The REXML gem 3.3.6 or later include the patch to fix the vulnerability. Workarounds Don't parse untrusted XMLs with tree parser API. References https://www.ruby-lang.org/en/news/2024/08/22/dos-rexml-cve-2024-43398/ : An announce on www.ruby-lang.org
