CVE-2026-27695: Zeroae Zae-Limiter

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Zeroae Zae-Limiter: before 0.10.1 (fixed in 0.10.1)
