CVE-2026-35523 (GCVE-0-2026-35523)

Vulnerability from cvelistv5 – Published: 2026-04-07 15:58 – Updated: 2026-04-09 16:18

Title
Authentication bypass in strawberry-graphql via legacy graphql-ws WebSocket subprotocol
Summary
Strawberry GraphQL is a library for creating GraphQL APIs. Strawberry up until version 0.312.3 is vulnerable to an authentication bypass on WebSocket subscription endpoints. The legacy graphql-ws subprotocol handler does not verify that a connection_init handshake has been completed before processing start (subscription) messages. This allows a remote attacker to skip the on_ws_connect authentication hook entirely by connecting with the graphql-ws subprotocol and sending a start message directly, without ever sending connection_init. This vulnerability is fixed in 0.312.3.

CVE-2026-35526 (GCVE-0-2026-35526)

Vulnerability from cvelistv5 – Published: 2026-04-07 15:23 – Updated: 2026-04-08 14:55

Title
Strawberry GraphQL affected by a Denial of Service via unbounded WebSocket subscriptions
Summary
Strawberry GraphQL is a library for creating GraphQL APIs. Prior to 0.312.3, Strawberry GraphQL's WebSocket subscription handlers for both the graphql-transport-ws and legacy graphql-ws protocols allocate an asyncio.Task and associated Operation object for every incoming subscribe message without enforcing any limit on the number of active subscriptions per connection. An unauthenticated attacker can open a single WebSocket connection, send connection_init, and then flood subscribe messages with unique IDs. Each message unconditionally spawns a new asyncio.Task and async generator, causing linear memory growth and event loop saturation. This leads to server degradation or an OOM crash. This vulnerability is fixed in 0.312.3.
