{"id":"CVE-2026-54608","state":"PUBLISHED","title":"MythicalDash: Unauthenticated payment bypass in Stripe success-redirect endpoint allows arbitrary free credit top-up","description":"MythicalDash is a Pterodactyl client area. In 3.5.4-aurora and earlier, GET /api/stripe/process in backend/app/Api/System/Gateways/Stripe.php creates a pending row in mythicaldash_stripe_payments before Stripe checkout succeeds and embeds the payment code in the success redirect, while GET /api/stripe/processed accepts that code without constructing a Session, checking ownership, or retrieving the Stripe Checkout Session to require payment_status to be paid and amount_total to match the expected charge. An ordinary authenticated user can request an attacker-selected coins amount, abandon or fail payment, and submit the pending code directly to the unauthenticated processed endpoint. StripeDB::isPending() then permits User::addCreditsAtomic() to grant the unpaid amount and mark the row processed even though Stripe has not confirmed payment. This permits arbitrary free virtual-currency top-ups and direct financial loss through consumption of hosting resources. No fixed version is available as of this review.","publishedAt":"2026-09-17T21:48:39.201Z","updatedAt":"2026-09-18T13:12:23.118Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["MythicalLTD MythicalDash"],"affected":[{"vendor":"MythicalLTD","product":"MythicalDash","versions":[{"version":"<= 3.5.4-aurora","status":"affected"}]}],"references":["https://github.com/MythicalLTD/MythicalDash/security/advisories/GHSA-qmh4-5v7g-42jq","https://github.com/MythicalLTD/MythicalDash/commit/188d4c4ed80b8d364b0c4605a9e38ceaab746e39"],"weaknesses":["CWE-345","CWE-862"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54608.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54608","state":"PUBLISHED","datePublished":"2026-09-17T21:48:39.201Z","dateUpdated":"2026-09-18T13:12:23.118Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T19:45:23.540Z"},"containers":{"cna":{"title":"MythicalDash: Unauthenticated payment bypass in Stripe success-redirect endpoint allows arbitrary free credit top-up","descriptions":[{"lang":"en","value":"MythicalDash is a Pterodactyl client area.
