Kerentanan Inefficient Algorithmic Complexity. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.

Deskripsi (NVD)

t-digest versions 3.1 through 3.3 fail to validate centroid means during deserialization in MergingDigest.fromBytes, allowing attackers to inject NaN values that bypass validation checks. Attackers can craft malicious serialized digests containing NaN centroids that degrade sorting performance from O(n log n) to O(n squared), causing severe processing delays during merge operations.
