Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

New API versions before 1.0.0-rc.11 are vulnerable. Unauthenticated requests to the Stripe, Creem and Waffo payment webhook endpoints, when those webhooks are enabled, could force large memory use and log growth before signature checks reject them, which can cause denial of service. Upgrade to 1.0.0-rc.11, which limits the size of anonymous request bodies; the limit is set by ANONYMOUS_REQUEST_BODY_LIMIT_KB and defaults to 512 KiB. If upgrading is not possible, disable unused payment webhooks and enforce request body limits at a reverse proxy or load balancer.
