Vulnerabilities

Strawberry GraphQL is a library for creating GraphQL APIs. In versions 0.172.0 through0.315.6, the MaxAliasesLimiter extension in Strawberry fails to account for the multiplicative/amplification effect of FragmentSpreadNode. While it correctly counts static aliases within the AST it does not consider how many times a fragments internal aliases are expanded during execution. this allows an attacker to bypass alias limits and force the server to resolve and render a significantly higher number of aliases than allowed, potentially leading to a dos via resource exhaustion. Version 0.315.7 contains a fix for the issue.

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.

Strawberry GraphQL is a library for creating GraphQL APIs. Prior to version 0.243.0, multipart file upload support as defined in the GraphQL multipart request specification was enabled by default in all Strawberry HTTP view integrations. This made all Strawberry HTTP view integrations vulnerable to cross-site request forgery (CSRF) attacks if users did not explicitly enable CSRF preventing security mechanism for their servers. Additionally, the Django HTTP view integration, in particular, had an exemption for Django's built-in CSRF protection (i.e., the `CsrfViewMiddleware` middleware) by default. In affect, all Strawberry integrations were vulnerable to CSRF attacks by default. Version `v0.243.0` is the first `strawberry-graphql` including a patch.

Incorrect access control in the install directory (C:\Strawberry) of StrawberryPerl v5.32.1.1 and below allows authenticated attackers to execute arbitrary code via overwriting binaries located in the directory.
