CVE-2025-27219 (GCVE-0-2025-27219)
Vulnerability from nvd
Published
2025-03-03 00:00
Modified
2025-11-03 21:13
Severity ?
5.8 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L
CWE
  • CWE-770 - Allocation of Resources Without Limits or Throttling
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.

CVE-2025-27219 (GCVE-0-2025-27219)
Vulnerability from cvelistv5
Published
2025-03-03 00:00
Modified
2025-11-03 21:13
Severity ?
5.8 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L
CWE
  • CWE-770 - Allocation of Resources Without Limits or Throttling
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.
