Unauthenticated quadratic CPU-exhaustion DoS disclosed in graphql-go/graphql up to v0.8.1 via OverlappingFieldsCanBeMergedRule; no fixed version exists.

Evgenios Gkritsis publicly disclosed an algorithmic-complexity denial-of-service flaw in github.com/graphql-go/graphql affecting all released versions up to and including v0.8.1. The defect is triggered via the OverlappingFieldsCanBeMergedRule validation, is unauthenticated and network-reachable, and causes quadratic CPU exhaustion. No fixed version exists; the disclosure was public because the project has no private security-reporting channel or SECURITY.md.

Cloudflare Workers Spectre Attack Leaks JWT From Co

Researchers demonstrated a remote Spectre attack leaking a JWT between co-located Cloudflare Workers at 12 bits per second, 360x the 2021 rate.

Security researchers showed a remote Spectre attack against Cloudflare Workers that leaked a JWT from a co-located Worker at up to 12 bits per second with 99.16% accuracy, 360 times the 2021 demonstration rate. The attack exploited weaknesses in DyPrIs dynamic process isolation, where long-lived Durable Object invocations could run before isolation and WebSocket-heavy I/O suppressed the branch-misprediction signal. Cloudflare deployed improved DyPrIs, the V8 Sandbox, and MPK-based in-process isolation, and found no indicators of active exploitation over three years.
