0 CVE-2026-72686 is a medium severity vulnerability in Elasticsearch where a low-privileged authenticated user can cause a denial of service by submitting a crafted input that triggers uncontrolled recursion during input validation. This recursion exhausts the thread's stack, causing the node process to terminate unexpectedly. The flaw affects multiple Elasticsearch versions prior to fixed releases. A patch is available to address this issue. Join the discussion | GCVE Database | 08/19/2026, 08:39:50 UTC Added: 08/19/2026, 13:50:41 UTC |
A flaw in Elasticsearch allows a low-privileged authenticated user to submit a single request containing a crafted user-supplied input. A specific internal component validates the input using a recursive routine and applies no bound to the length of the value being validated, so the validation causes the thread to exhaust its stack. The resulting fatal error is not handled by the surrounding execution paths and terminates the affected node process, producing a denial of service.
