This is a race condition that occurs rarely in normal usage; the typical period in which this is possible is limited to at most a few seconds after the permission change.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-362"],"references":["http://www.securityfocus.com/bid/96464","https://support.f5.com/csp/article/K47284724","http://www.securityfocus.com/bid/96464","https://support.f5.com/csp/article/K47284724"],"products":["f5:big-ip_access_policy_manager","f5:big-ip_advanced_firewall_manager","f5:big-ip_analytics","f5:big-ip_application_acceleration_manager","f5:big-ip_application_security_manager","f5:big-ip_domain_name_system","f5:big-ip_link_controller","f5:big-ip_local_traffic_manager","f5:big-ip_policy_enforcement_manager","f5:big-ip_websafe"],"source":"nvd","synced_at":"2026-10-19T20:42:28.077359912+00:00"},"epss":{"cve":"CVE-2016-9256","score":0.01041,"percentile":0.64036,"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).
