DescriptionGitHub Advisory

zae-limiter is a rate limiting library using the token bucket algorithm. Prior to version 0.10.1, all rate limit buckets for a single entity share the same DynamoDB partition key (namespace/ENTITY#{id}). A high-traffic entity can exceed DynamoDB's per-partition throughput limits (~1,000 WCU/sec), causing throttling that degrades service for that entity - and potentially co-located entities in the same partition. Version 0.10.1 fixes the issue.

AnalysisAI

Zae-Limiter versions up to 0.10.1 is affected by allocation of resources without limits or throttling (CVSS 4.3).
