CVE-2026-104893

Medium

Description

Plane is an open-source project management tool. Prior to 1.4.0, GET /api/users/api-tokens/ allows an authenticated user to retrieve API-token records, while PATCH /api/users/api-tokens/{token_id}/ allows the user to modify the token's allowed_rate_limit field without server-side validation or a maximum value. A user can raise the limit arbitrarily and bypass intended API rate-limiting controls, enabling high-volume automated requests, backend resource abuse, and possible resource exhaustion. This issue is fixed in 1.4.0.
