NOTE: it could be argued that this not a vulnerability in PHP itself, rather a design limitation that enables certain attacks against session handlers that do not account for this limitation.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://secunia.com/advisories/21573","http://securityreason.com/securityalert/1466","http://www.hardened-php.net/advisory_052006.128.html","http://www.osvdb.org/28233","http://www.osvdb.org/28273"],"products":["php:php"],"source":"nvd","synced_at":"2026-10-19T19:42:44.451428143+00:00"},"epss":{"cve":"CVE-2006-4433","score":0.01825,"percentile":0.7881,"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).
