NOTE: it is not clear whether this problem can be exploited for code execution. If not, then perhaps the user-assisted nature of the attack should exclude the issue from inclusion in CVE.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://securityreason.com/securityalert/290","http://www.securityfocus.com/archive/1/420006/100/0/threaded","http://www.securityfocus.com/bid/15999","http://securityreason.com/securityalert/290","http://www.securityfocus.com/archive/1/420006/100/0/threaded"],"products":["rarlab:winrar"],"source":"nvd","synced_at":"2026-10-19T19:40:09.211843075+00:00"},"epss":{"cve":"CVE-2005-4474","score":0.02045,"percentile":0.81191,"date":"2026-10-31"},"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).
