When this check fails, libcurl would free the memory for the fingerprint before it returns an error message containing the (now freed) hash. This flaw risks inserting sensitive heap-based data into the error message that might be shown to users or otherwise get leaked and revealed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-416"],"references":["http://seclists.org/fulldisclosure/2023/Jul/47","http://seclists.org/fulldisclosure/2023/Jul/48","http://seclists.org/fulldisclosure/2023/Jul/52","https://hackerone.com/reports/1913733","https://security.gentoo.org/glsa/202310-12"],"products":["apple:macos","haxx:curl","netapp:clustered_data_ontap","netapp:h300s_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware","netapp:ontap_antivirus_connector"],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2023-28319","score":0.02489,"percentile":0.84517,"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).
