{"id":"CVE-2026-100708","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-100708","summary":"Froxlor before 2.3.13 returns the ssl_key_file column — which stores the raw PEM TLS private-key content — verbatim in the JSON responses of the Certificates.get and Certificates.listing…","details":"Froxlor before 2.3.13 returns the ssl_key_file column — which stores the raw PEM TLS private-key content — verbatim in the JSON responses of the Certificates.get and Certificates.listing API commands, because the results of the underlying domain_ssl_settings queries are passed through ApiCommand::response() without any field stripping or allowlist. 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":"2026-09-26T14:16:56.153","modified":"2026-09-26T14:16:56.373","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-6q2v-jjq5-m2c8"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.13-private-key-disclosure-via-certificates-api"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-26T14:16:56.373"}}
