Detailsinfo

A vulnerability classified as problematic has been found in milvus-io milvus up to 2.6.13. Affected is some unknown processing of the file internal/metastore/kv/rootcoord/kv_catalog.go of the component Grantee ID Hash Handler. The manipulation with an unknown input leads to a weak hash vulnerability. CWE is classifying the issue as CWE-328. The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). This is going to have an impact on confidentiality, integrity, and availability.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-10814. The exploitability is told to be difficult. Local access is required to approach this attack.
