CVE-2025-27219 (GCVE-0-2025-27219)

Vulnerability from cvelistv5 – Published: 2025-03-03 00:00 – Updated: 2025-11-03 21:13

Summary

In the CGI gem before 0.4.2 for Ruby, the CGI::Cookie.parse method in the CGI library contains a potential Denial of Service (DoS) vulnerability. The method does not impose any limit on the length of the raw cookie value it processes. This oversight can lead to excessive resource consumption when parsing extremely large cookies.

Severity ?

5.8 (Medium)

CVE-2024-43398 (GCVE-0-2024-43398)

Vulnerability from cvelistv5 – Published: 2024-08-22 14:14 – Updated: 2025-11-03 20:38

Title

REXML denial of service vulnerability

Summary

REXML is an XML toolkit for Ruby. 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. The REXML gem 3.3.6 or later include the patch to fix the vulnerability.

Severity ?

5.9 (Medium)
