CVE-2026-90582Network attack vector

Resource consumption via crafted Todo request body

Published Sep 13, 2026 · Updated Sep 13, 2026

Resource consumption in evanchiu serverless-todo 1.0.3 and 2.0.0 allows remote attackers to consume service resources via crafted API request bodies. The saveTodos function in src/index.js consumes resources while processing attacker-controlled event.body data, but the precise expensive operation is undisclosed. The API Todo endpoint must be remotely reachable, and the record does not distinguish whether exhaustion causes a hang, crash, or quota failure.
