CVE-2024-23444 [HIGH] CWE-311 CVE-2024-23444: It was discovered by Elastic engineering that when elasticsearch-certutil CLI tool is used with the It was discovered by Elastic engineering that when elasticsearch-certutil CLI tool is used with the csr option in order to create a new Certificate Signing Requests, the associated private key that is generated is stored on disk unencrypted even if the --pass parameter is passed in the command invocation.

CVE-2023-49921 [MEDIUM] CWE-532 CVE-2023-49921: An issue was discovered by Elastic whereby Watcher search input logged the search query results on D An issue was discovered by Elastic whereby Watcher search input logged the search query results on DEBUG log level. This could lead to raw contents of documents stored in Elasticsearch to be printed in logs. Elastic has released 8.11.2 and 7.17.16 that resolves this issue by removing this excessive logging. This issue only affects users that use Wat

CVE-2024-37280 [MEDIUM] CWE-122 CVE-2024-37280: A flaw was discovered in Elasticsearch, affecting document ingestion when an index template contains A flaw was discovered in Elasticsearch, affecting document ingestion when an index template contains a dynamic field mapping of “passthrough” type. Under certain circumstances, ingesting documents in this index would cause a StackOverflow exception to be thrown and ultimately lead to a Denial of Service. Note that passthrough fields is an experiment

CVE-2024-23445 [MEDIUM] CWE-922 CVE-2024-23445: It was identified that if a cross-cluster API key https://www.elastic.co/guide/en/elasticsearch/ref It was identified that if a cross-cluster API key https://www.elastic.co/guide/en/elasticsearch/reference/8.14/security-api-create-cross-cluster-api-key.html#security-api-create-cross-cluster-api-key-request-body restricts search for a given index using the query or the field_security parameter, and the same cross-cluster API key also grants replica
