Prior to version 4.2.14, two related startup defects created a window during which only the single compile-time baseline rule was enforced by opfilter. All managed (MDM-delivered) and user-defined file-access rules were not applied until the user interacted with policies through the GUI, triggering a policy mutation over XPC. This issue has been patched in version 4.2.14.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-269"],"references":["https://github.com/craigjbass/clearancekit/commit/56d617b778c571e3c29b803636d9807940992daa","https://github.com/craigjbass/clearancekit/commit/ddfdacb2633681bbd9c2f41dbd536ea039386628","https://github.com/craigjbass/clearancekit/security/advisories/GHSA-fpmv-5wgw-qhhr"],"products":["craigjbass:clearancekit"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-34218","score":0.00203,"percentile":0.10317,"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).
