What the CVE records say
CVE-2026-72686 — 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.
Impact
Successful exploitation of this vulnerability could lead to Denial of Service (DoS).
Affected products
- Brocade SAN Navigator (SANnav)
