{"schema":"threatline.record/2","record":{"id":"CVE-2026-107852","aliases":["GHSA-rf56-676w-hj4g"],"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.","categories":["Unclassified"],"product":"Jexactyl","vendor":"Jexactyl","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107852","source_modified_at":"2026-10-14T02:11:26.450Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Jexactyl","vendor":"Jexactyl","versions":[{"status":"affected","version":"< 4.0.5"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","source_modified_at":"2026-10-09T20:27:24Z","fetched_at":"2026-10-23T20:00:35.122048Z","package":{"ecosystem":"composer","name":"jexactyl/jexactyl"},"range":"<= 4.0.1"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.0016,"percentile":0.04859,"score_date":"2026-10-23"},"published_at":"2026-10-09T20:28:06.513Z","modified_at":"2026-10-14T02:11:26.450Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107852","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T02:11:26.450Z"},{"source":"GitHub Advisory Database","url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","fetched_at":"2026-10-23T20:00:35.122048Z","source_modified_at":"2026-10-09T20:27:24Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107852","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Jexactyl/Jexactyl/security/advisories/GHSA-rf56-676w-hj4g","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/Jexactyl/Jexactyl/commit/fdee722c560ac13dc2d26271912203a6085dffe3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/Jexactyl/Jexactyl/releases/tag/v4.0.5","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T02:11:02.263904Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T02:11:26.450Z","content_hash":"dade72cf018effa03c1aa269f240c846c256a912e1d27c22ab6b753051a42755"}}
