mediumpriority · track · 0EPSS 0.004 · 30 %ileDEEUUSEPSS · scored 2026-10-27
A flaw in Elasticsearch allows a low-privileged authenticated user who can index documents to submit a single small document containing a crafted user-supplied input. Processing one such document occupies a worker thread from a bounded pool for a disproportionate amount of time, degrading the availability of indexing operations on the affected node.
