{"id":"CVE-2026-107852","summary":"Jexactyl: Stripe checkout confirmation accepts mismatched-currency/amount payments as full payment (payment forgery)","details":"Jexactyl is a customisable game management panel and billing system. Prior to 4.0.5, the POST /api/client/billing/stripe/process endpoint accepts a client-supplied Stripe Checkout Session when payment_status is paid but does not compare amount_total or currency with the referenced order and configured billing currency. On an instance where the billing module is enabled and a Stripe secret key is configured, an authenticated client can therefore complete a lower-value or mismatched-currency payment and cause the order to be processed, provisioning, renewing, upgrading, or unsuspending the purchased server for less than the required price. This issue is fixed in version 4.0.5.","aliases":["GHSA-rf56-676w-hj4g"],"modified":"2026-10-10T10:45:15.896838638Z","published":"2026-10-09T20:28:06.513Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-345"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107852.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107852.json"},{"type":"FIX","url":"https://github.com/Jexactyl/Jexactyl/commit/fdee722c560ac13dc2d26271912203a6085dffe3"},{"type":"WEB","url":"https://github.com/Jexactyl/Jexactyl/releases/tag/v4.0.5"},{"type":"ADVISORY","url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107852"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jexactyl/jexactyl","events":[{"introduced":"0"},{"fixed":"4bccd3d0eaf34d9db5255842d18340d08af90400"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.0.5"}],"source":"AFFECTED_FIELD"}}],"versions":["v4.0.4","v4.0.3","v4.0.2","v4.0.1","v4.0.0","v4.0.0-rc3","v4.0.0-rc2","v4.0.0-rc1","v4.0.0-beta7","v4.0.0-beta6","v4.0.0-beta5","v4.0.0-beta4","v4.0.0-beta3","v4.0.0-beta2","v4.0.0-beta1","v1.11.0-rc.2","v1.11.0-rc.1","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.0","v1.6.6","v1.6.5","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.3.2","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0-rc.7","v1.0.0-rc.6","v1.0.0-rc.5","v1.0.0-rc.4","v1.0.0-rc.3","v1.0.0-rc.1","v0.5.0","v0.4.1-beta","v0.4.0-beta","v0.3.0-beta","v0.2.0-beta","v0.1.2-beta","v0.1.1-beta","v0.1.0-beta"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107852.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
