A low-privileged authenticated customer API caller can retrieve the private keys of their own domains' certificates, including Let's Encrypt keys that Froxlor generates server-side and stores root-only (0600) and to which the customer otherwise has no filesystem access; reseller and customers_see_all admin accounts can dump the private keys of other principals through the same sink. Disclosed keys enable domain impersonation, passive decryption of captured TLS traffic, and active machine-in-the-middle attacks.","published":"2026-09-26T14:16:56.000Z","lastModified":"2026-09-28T15:17:11.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":7.1,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.00159,"percentile":0.05016,"date":"2026-10-27","history":[{"date":"2026-09-27","score":0.00129,"percentile":0.02124}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.16%).
