Vulnerability Details

**CVEID:**CVE-2023-31418 DESCRIPTION: Elastic Elasticsearch is vulnerable to a denial of service, caused by uncontrolled resource consumption. By sending a moderate number of malformed HTTP requests, a remote attacker could exploit this vulnerability to force an Elasticsearch node to exit with an OutOfMemory error.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/270341 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

**CVEID:**CVE-2023-46673 DESCRIPTION: Elastic Elasticsearch is vulnerable to a denial of service, caused by improper handling of exceptional conditions. By sending a specially crafted request using the Simulate Pipeline API, a remote authenticated attacker could exploit this vulnerability to cause an Elasticsearch node to crash.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/272207 for the current score.
