A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a \"sister server\" to effectively cause a denial of service for a sibling site on the same second level domain using this method.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-770"],"references":["http://seclists.org/fulldisclosure/2022/Oct/28","http://seclists.org/fulldisclosure/2022/Oct/41","https://cert-portal.siemens.com/productcert/pdf/ssa-333517.pdf","https://hackerone.com/reports/1569946","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEV6BR4MTI3CEWK2YU2HQZUW5FAS3FEY/"],"products":["apple:macos","debian:debian_linux","fedoraproject:fedora","haxx:curl","netapp:clustered_data_ontap","netapp:element_software","netapp:h300s_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware","netapp:hci_management_node","netapp:solidfire","siemens:scalance_sc622-2c_firmware","siemens:scalance_sc626-2c_firmware","siemens:scalance_sc632-2c_firmware","siemens:scalance_sc636-2c_firmware","siemens:scalance_sc642-2c_firmware","siemens:scalance_sc646-2c_firmware","splunk:universal_forwarder"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-32205","score":0.31497,"percentile":0.98272,"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).
