ash_typescript is vulnerable to Uncontrolled Resource Consumption
87
High Risk
This Affects:
ash_typescriptTL;DR
FieldFormatter.convert_to_field_atom/2 in ash_typescript calls String.to_atom/1 on client supplied RPC field names that have no existing atom. Atoms are never garbage collected, so unauthenticated requests with many distinct unknown field names exhaust the BEAM atom table. When the limit is reached the node aborts with a system_limit error, taking down every application on that VM. The fix stops creating atoms from unvalidated client field names.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you expose an AshTypescript RPC endpoint reachable with client supplied field names.
Background info
ash_typescript is vulnerable to Uncontrolled Resource Consumption in versions 0.1.0 - 0.17.3.
How to fix this
Upgrade the ash_typescript library to the patch version.
