Description (CNA)
A flaw was found in search-indexer. This vulnerability allows a registered and authenticated managed cluster to tamper with or delete another cluster's indexed search data. This is possible because the delta-sync write paths in search-indexer do not properly restrict UPDATE/DELETE operations to data owned by the calling cluster. An attacker could exploit this by crafting specific user identifiers (UIDs) with a different cluster's prefix.
