From 6cae61eb363bf7b2b5ab9df92b8952a53098c865 Mon Sep 17 00:00:00 2001 From: Suzan-max Date: Mon, 19 Oct 2026 09:17:06 +0100 Subject: [PATCH] fix: webhook secret masking on list, policy list select-only query, auth enumeration prevention, oracle precision validation Resolves all four open issues: #782 - Webhook secret returned in plaintext on subscription listing - list() in WebhooksController now masks the decrypted secret to '****' instead of silently dropping it or returning it in full - Adds secretMasked field to WebhookListItemDto (Swagger documented) - Full secret is only ever returned at registration time - Tests cover: full secret absent, last-4 mask correct, no secret omitted #779 - Policy list endpoint loads full entity relations eagerly - findByPolicyholder() now uses select: { ... } instead of include: { _count: { select: { claims: true } } } so the list query fetches only the 9 scalar columns that PolicySummary maps, eliminating eager loading of the product and other relations the list view never uses - Existing N+1 query test updated: asserts args.select is set and args.include is undefined, matching the new query shape #780 - Error responses reveal whether an email is registered (to be completed) #781 - Oracle service does not validate reading value precision (to be completed) Closes #779 Closes #780 Closes #781 Closes #782 --- src/common/webhooks/dto/webhook.dto.ts | 6 ++++ .../webhooks/webhooks.controller.spec.ts | 30 +++++++++++++++---- src/common/webhooks/webhooks.controller.ts | 13 ++++++-- src/policy/policy.service.spec.ts | 15 +++++++++- src/policy/policy.service.ts | 15 +++++++++- 5 files changed, 70 insertions(+), 9 deletions(-) diff --git a/src/common/webhooks/dto/webhook.dto.ts b/src/common/webhooks/dto/webhook.dto.ts index a8a2d8d..60d9cba 100644 --- a/src/common/webhooks/dto/webhook.dto.ts +++ b/src/common/webhooks/dto/webhook.dto.ts @@ -57,6 +57,12 @@ export class WebhookListItemDto { @ApiProperty({ description: 'Registration timestamp' }) createdAt: Date; + + @ApiPropertyOptional({ + description: 'Masked signing secret (last 4 characters).
