NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.","published":"2007-06-20T22:30:00.000Z","lastModified":"2026-06-16T22:41:27.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"2.0","score":4.9,"severity":"MEDIUM","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:C"},"cwe":["CWE-94"],"affected":["apache/http server"],"epss":{"score":0.0089,"percentile":0.59115,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.89%).
