NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in Simple Machines Forum.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://retrogod.altervista.org/smf_11rc2_local_incl.html","http://retrogod.altervista.org/smf_11rc2_lock.html","http://securityreason.com/securityalert/1475","http://www.securityfocus.com/archive/1/444053/100/100/threaded","http://www.simplemachines.org/community/index.php?topic=107112.0"],"products":["simple_machines:simple_machines_forum"],"source":"nvd","synced_at":"2026-10-19T19:42:44.451428143+00:00"},"epss":{"cve":"CVE-2006-4467","score":0.0185,"percentile":0.7911,"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).
