{
    "lastseen": "",
    "description": "Plane is an an open-source project management tool. Prior to 1.3.0, a vulnerability was identified in Plane's authentication flow where a user's email address is included as a query parameter in the URL during error handling (e.g., when an invalid magic code is submitted). Transmitting personally identifiable information (PII) via GET request query strings is classified as an insecure design practice. The affected code path is located in the authentication utility module (packages/utils/src/auth.ts). This vulnerability is fixed in 1.3.0.",
