Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Administrative and batch operations can be manipulated to trigger cross-namespace state migrations or workflow modifications if input namespaces are not validated strictly against the worker's own bound namespace. This class of bugs is tracked globally under CVE-2026-5199.
Auth Bypass: Streaming endpoints and cross-namespace command trees bypass core authorizers unless targeted validations are recursively performed on both parent-child relationships and nested sub-operations in ExecuteMultiOperation paths.
Denial of Service: Without hard, cumulative limits enforced on the collection sizes of pending child workflows, signals, memos, and search attributes, malicious or malfunctioning workflows can trigger massive memory exhaustion and storage layer starvation.
