CyberRota Analysis
AI-GeneratedThe Kurrier API prior to version 1.2.4 lacks proper ownership checks for authenticated requests, allowing attackers with valid API keys to access and enumerate webhook and identity resources belonging to other users. This vulnerability could lead to unauthorized exposure of sensitive resource metadata, potentially impacting user privacy and security. Organizations using Kurrier should prioritize upgrading to version 1.2.4 to mitigate this risk.

Original NVD Description
Kurrier is a modern, self-hosted workspace for email, calendar, contacts, and storage. Prior to 1.2.4, Kurrier API endpoints for listing and retrieving webhook and identity resources did not enforce ownership checks for authenticated API requests. An attacker with a valid API key could use another account's identifiers to read and enumerate webhook and identity resources belonging to that account through apps/worker/server/routes/api/kurrier/webhooks/[id].get.ts, apps/worker/server/routes/api/kurrier/webhooks/index.get.ts, apps/worker/server/routes/api/kurrier/identities/[id].get.ts, and apps/worker/server/routes/api/kurrier/identities/index.get.ts. Anonymous requests and invalid API keys were rejected, and cross-user modification operations were blocked, but affected GET and list operations could expose another user's resource metadata. This issue is fixed in version 1.2.4.
