Potential fix for https://github.com/balena-io-modules/pinejs-client-js/security/code-scanning/1
General fix: validate computed property keys at runtime before indexing/writing, or use a structure immune to prototype keys (e.g.,
Map).Best minimal fix here: add a strict runtime allowlist check in
on(...)so only'data'and'error'are accepted, then proceed with existing logic unchanged.In
src/index.ts, insideon(...)(around lines 304–318), insert a guard beforethis.subscribers[name]access:name !== 'data' && name !== 'error', throw aTypeError.No new imports/dependencies are required.
