Last modified
CVE-2026-72685 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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.. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
