NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-94"],"references":["http://osvdb.org/37050","http://security.psnc.pl/files/apache_report.pdf","http://securityreason.com/securityalert/2814","http://www.securityfocus.com/archive/1/469899/100/0/threaded","http://www.securityfocus.com/archive/1/471832/100/0/threaded"],"products":["apache:http_server"],"source":"nvd","synced_at":"2026-10-19T19:46:28.846926071+00:00"},"epss":{"cve":"CVE-2007-3303","score":0.0089,"percentile":0.59385,"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).
