If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-201"],"references":["https://hackerone.com/reports/1553301","https://security.gentoo.org/glsa/202212-01","https://security.netapp.com/advisory/ntap-20220609-0009/","https://hackerone.com/reports/1553301","https://security.gentoo.org/glsa/202212-01"],"products":["haxx:curl","netapp:clustered_data_ontap","netapp:h300s_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware","netapp:hci_bootstrap_os","netapp:hci_compute_node","netapp:solidfire\\,_enterprise_sds_\\&_hci_storage_node","netapp:solidfire_\\&_hci_management_node","splunk:universal_forwarder"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-27779","score":0.02785,"percentile":0.86304,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
