Memory Allocation with Excessive Size Value CWE-789 in the ES|QL query processing of Elasticsearch can lead to denial of service via Excessive Allocation CAPEC-130. An authenticated user able to submit ES|QL queries could send a specially crafted query whose evaluation allocates an unbounded amou...

PT-2026-71757

Elasticsearch does not enforce an upper bound on a user-supplied count accepted by a search highlighting option, and the allocation derived from that count is not accounted against any circuit breaker. An authenticated user holding only read privileges on a single searchable index can submit one...

PT-2026-71795

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...

Name of the Vulnerable Software and Affected Versions Elasticsearch affected versions not specified Description The native inference process used to evaluate uploaded machine learning models fails to validate that a memory address offset supplied within the model remains within the bounds of the...

PT-2026-71755

Uncontrolled Recursion CWE-674 in the Elasticsearch wildcard matching helper can lead to a denial of service via Excessive Allocation CAPEC-130. The matcher used to resolve wildcard patterns against names is implemented recursively and had no bound on recursion depth or on the total number of mat...

PT-2026-71753

Name of the Vulnerable Software and Affected Versions Kibana Fleet affected versions not specified Description Improper privilege management in Kibana Fleet allows for privilege escalation. This occurs when an integration policy declares extra data streams for writing, which Fleet then adds to th...

Improper Input Validation

Apache Camel is vulnerable to Improper Input Validation. The vulnerability is due to Elasticsearch control headers lacking the Camel prefix and therefore bypassing Camel's inbound HTTP header filtering, which allows an unauthenticated attacker to inject user-controlled headers and override...
