{"cve":"CVE-2026-25963","nvd":{"published":"2026-02-26T03:16:04.350","modified":"2026-06-17T10:25:30.157","status":"Analyzed","description":"Fleet is open source device management software. In versions prior to 4.80.1, a broken authorization check in Fleet’s certificate template deletion API could allow a team administrator to delete certificate templates belonging to other teams within the same Fleet instance. Fleet supports certificate templates that are scoped to individual teams. In affected versions, the batch deletion endpoint validated authorization using a user-supplied team identifier but did not verify that the certificate template IDs being deleted actually belonged to that team. As a result, a team administrator could delete certificate templates associated with other teams, potentially disrupting certificate-based workflows such as device enrollment, Wi-Fi authentication, VPN access, or other certificate-dependent configurations for the affected teams. This issue does not allow privilege escalation, access to sensitive data, or compromise of Fleet’s control plane. Impact is limited to integrity and availability of certificate templates across teams. Version 4.80.1 patches the issue. If an immediate upgrade is not possible, administrators should restrict access to certificate template management to trusted users and avoid delegating team administrator permissions where not strictly required.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U","score":1.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H","score":6.5},"cwes":["CWE-863"],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-5jvp-m9h4-253h"],"products":["fleetdm:fleet"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-25963","score":0.00208,"percentile":0.10981,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5jvp-m9h4-253h","url":"https://osv.dev/vulnerability/GHSA-5jvp-m9h4-253h","summary":"Fleet: Authorization Bypass in certificate template batch deletion for team administrators","modified":"2026-03-09T02:03:54.515789664Z","packages":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","ranges":["<4.80.1"],"fixed":["4.80.1"]}]},{"id":"GO-2026-4561","url":"https://osv.dev/vulnerability/GO-2026-4561","summary":"Fleet: Authorization Bypass in certificate template batch deletion for team administrators in github.com/fleetdm/fleet","modified":"2026-03-09T02:03:54.515789Z","packages":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","ranges":["<4.80.1"],"fixed":["4.80.1"]}]}],"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).
