Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the BatchingProcessor. An attacker can exhaust CPU resources and degrade or deny service by continuously filling the asynchronous export buffer while the exporter is backpressured, causing the processor to enter a tight loop and repeatedly retry operations without waiting.
