Prior to 4.81.1, the Orbit agent's FileVault disk encryption key rotation flow on collects a local user's password via a GUI dialog and interpolates it directly into a Tcl/expect script executed via exec.Command(\"expect\", \"-c\", script). Because the password is inserted into Tcl brace-quoted send {%s}, a password containing } terminates the literal and injects arbitrary Tcl commands. Since Orbit runs as root, this allows a local unprivileged user to escalate to root privileges. This vulnerability is fixed in 4.81.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-78"],"references":["https://github.com/fleetdm/fleet/security/advisories/GHSA-rphv-h674-5hp2"],"products":["fleetdm:fleet"],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-27806","score":0.00111,"percentile":0.01302,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-rphv-h674-5hp2","url":"https://osv.dev/vulnerability/GHSA-rphv-h674-5hp2","summary":"Fleet Affected by Local Privilege Escalation via Tcl Command Injection in Orbit","modified":"2026-06-26T20:30:09.739955430Z","packages":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","ranges":["<4.81.1"],"fixed":["4.81.1"]}]},{"id":"GO-2026-5634","url":"https://osv.dev/vulnerability/GO-2026-5634","summary":"Fleet Affected by Local Privilege Escalation via Tcl Command Injection in Orbit in github.com/fleetdm/fleet","modified":"2026-06-25T23:01:37.519165109Z","packages":[{"ecosystem":"Go","name":"github.com/fleetdm/fleet/v4","purl":"pkg:golang/github.com/fleetdm/fleet/v4","ranges":["<4.81.1"],"fixed":["4.81.1"]}]}],"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).
