Highlights
Denial of Service: 9 prior fixes. Scrutinize any change in this area.
pkg/workflows/wasm/host/execution.go: most-fixed (5 issues). Treat as high-risk during review.
9 high-severity fixes in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Multiple independent fixes target unbounded guest-controlled operations (subscriptions, capability calls, logs, memory copies) and runtime resource limits; the WASM host is the most frequently patched attack surface.
Auth Bypass: Three distinct fixes enforce authorization on capability execution and ingress: restrictions on workflow execution, binding enclave config to attestation, and adding auth headers to chip ingress. Missing any of these allows unauthorized access.
Signature Verification Bypass: Signature verification was bypassed by not checking the public key prefix in the signature blob, allowing forged signatures.
