{"cve":"CVE-2026-27465","nvd":{"published":"2026-02-26T03:16:04.520","modified":"2026-06-17T10:27:11.820","status":"Analyzed","description":"Fleet is open source device management software. In versions prior to 4.80.1, a vulnerability in Fleet’s configuration API could expose Google Calendar service account credentials to authenticated users with low-privilege roles. This may allow unauthorized access to Google Calendar resources associated with the service account. Fleet returns configuration data through an API endpoint that is accessible to authenticated users, including those with the lowest-privilege “Observer” role. In affected versions, Google Calendar service account credentials were not properly obfuscated before being returned. As a result, a low-privilege user could retrieve the service account’s private key material. Depending on how the Google Calendar integration is configured, this could allow unauthorized access to calendar data or other Google Workspace resources associated with the service account. This issue does not allow escalation of privileges within Fleet or access to device management functionality. Version 4.80.1 patches the issue. If an immediate upgrade is not possible, administrators should remove the Google Calendar integration from Fleet and rotate the affected Google service account credentials.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U","score":1.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-201"],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-2v6m-6xw3-6467"],"products":["fleetdm:fleet"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27465","score":0.00275,"percentile":0.199,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2v6m-6xw3-6467","url":"https://osv.dev/vulnerability/GHSA-2v6m-6xw3-6467","summary":"Fleet: Sensitive Google Calendar credentials disclosed to low-privileged users","modified":"2026-03-09T02:03:43.785004703Z","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-2026-4560","url":"https://osv.dev/vulnerability/GO-2026-4560","summary":"Fleet: Sensitive Google Calendar credentials disclosed to low-privileged users in github.com/fleetdm/fleet","modified":"2026-03-09T02:03:43.785004Z","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).
