Overview
Affected versions of this package are vulnerable to Reachable Assertion in the $_internalConvertBucketIndexStats process when handling input that is not timeseries data. An attacker can cause the server to crash by constructing a pipeline where this stage is placed before $facet, leading to an unexpected signal being sent to TeeBuffer and triggering a hard invariant assertion.
