{"id":"CVE-2026-107852","published":"2026-10-09T21:17:03.080","lastModified":"2026-10-14T03:17:15.083","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-345"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Jexactyl/Jexactyl/commit/fdee722c560ac13dc2d26271912203a6085dffe3","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/releases/tag/v4.0.5","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","tags":[]}],"exploitRefs":[{"url":"https://github.com/Jexactyl/Jexactyl/commit/fdee722c560ac13dc2d26271912203a6085dffe3","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/releases/tag/v4.0.5","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","tags":[]},{"url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","tags":[]}],"hasPoc":true,"ai":null}
