The vulnerability exists due to insufficient validation of user-supplied input in CGI::Cookie.parse. A remote attacker can send a specially crafted HTTP request to the application and perform a denial of service (DoS) attack.

2) Inefficient regular expression complexity (CVE-ID: CVE-2025-27220)

CWE-ID: CWE-1333 - Inefficient Regular Expression Complexity

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
