What happened
Check Point Research reports five memory-corruption vulnerabilities in workerd, the native C++ runtime underlying Cloudflare Code Mode and Workers. Because workerd relies on V8 for in-process isolation of untrusted code, exploitation may enable sandbox escape, arbitrary code execution, or compromise of workloads hosted in Cloudflare’s serverless environments. The document is a research-feed aggregation; specific vulnerability identifiers and affected versions are not provided in the supplied content.
