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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":51,"depthScoreParts":{"impact":39.1,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":221203,"id":"CVE-2026-107852","ts":1792030812660,"field":"exploit_available","old":"false","new":"true"},{"seq":221202,"id":"CVE-2026-107852","ts":1792030812660,"field":"cvss","old":null,"new":"7.1"},{"seq":221201,"id":"CVE-2026-107852","ts":1792030812660,"field":"severity","old":"none","new":"high"}]}
