@sachinacharyaa is attempting to deploy a commit to the Superteam Team on Vercel. A member of the Team first needs to authorize it. |
WalkthroughPayment validation now supports positive partial payments for native SOL and token transfers. The verification handler scopes submission lookup by ChangesPayment verification
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR binds payment verification to the authenticated listing, but payment amount validation still accepts non-finite values that can bypass mismatch checks and persist invalid payment details. Merge should wait for this bounded payment-integrity issue to be fixed or explicitly accepted by the owner. Possibly related PRs

PR #1471 is ready for review. CodeRabbit passed with no actionable comments and there are no conflicts. The only failing check is Vercel because deployment authorization requires a Superteam team member. The security fix itself is limited to binding submission lookup to listingId. |

Reject non-finite expectedAmount values.
expectedAmount <= 0 accepts NaN and Infinity. Both values disable the amount-mismatch check. The add-payment endpoint also accepts truthy string values such as "NaN" and "Infinity", then persists them in paymentDetails.
Use !Number.isFinite(expectedAmount) || expectedAmount <= 0.

Updated to support partial project payments.
The expected amount now uses the remaining amount for project payments, and allowPartialPayment is enabled only for project listings. This also keeps the normal full-payment validation unchanged for non-project payments.

What does this PR do?
Fixes an authorization issue in external payment verification where a sponsor could submit a
submissionIdbelonging to a different listing.The submission lookup now also requires the authenticated
listingId:submissionIdis bound to the listing being authenticated.Where should the reviewer start?
src/pages/api/sponsor-dashboard/listings/verify-external-payment.tsSpecifically, the
prisma.submission.findManyquery in the payment verification handler.How should this be manually tested?
submissionIdfrom listing B.submissionIdto the external payment verification endpoint for listing A.Any background context you want to provide?
The endpoint previously authenticated the sponsor against the request's
listingId, but the subsequent submission lookup only filtered bysubmissionIdandisPaid.This allowed a submission from another listing to reach the payment verification/update flow.
This change binds the submission lookup to the authenticated listing as an additional authorization boundary.
What are the relevant issues?
Security fix for cross-listing submission authorization / IDOR in external payment verification.
