CVE-2026-56150 1 Elastic 1 Fleet Server 2026-07-06 N/A 6.5 MEDIUM
Allocation of Resources Without Limits or Throttling (CWE-770) in Fleet Server can lead to a denial of service via Excessive Allocation (CAPEC-130). An attacker can submit a specially crafted request to an upload endpoint that causes excessive memory consumption, which may render Fleet Server unavailable.
CVE-2026-56152 1 Elastic 1 Endpoint Security 2026-07-06 N/A 5.3 MEDIUM
Incorrect Authorization (CWE-863) in Elastic Defend can lead to unauthorized information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). Under certain conditions, a low-privileged authenticated user can access response action data that they are not authorized to view.
CVE-2026-49091 1 Elastic 1 Kibana 2026-07-02 N/A 8.0 HIGH
Improper Output Neutralization for Logs (CWE-117) in Kibana can lead to log injection via Log Injection-Tampering-Forging (CAPEC-93). An attacker can supply specially crafted input that is written to log files without proper neutralization. When the log files are subsequently viewed in a terminal that interprets control sequences, the injected content may alter the displayed log data.
CVE-2026-49087 1 Elastic 1 Kibana 2026-07-02 N/A 6.5 MEDIUM
Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user can submit a specially crafted bulk deletion request that causes excessive resource consumption, which may render Kibana unavailable.
CVE-2026-49088 1 Elastic 1 Kibana 2026-07-02 N/A 4.4 MEDIUM
Insertion of Sensitive Information into Log File (CWE-532) in Kibana can lead to information disclosure. When the optional application performance monitoring (APM) instrumentation is enabled, sensitive request header values could be recorded in application logs, where they may be accessible to operators with log access.
CVE-2026-56148 1 Elastic 1 Elasticsearch 2026-07-02 N/A 6.5 MEDIUM
Uncontrolled Recursion (CWE-674) in Elasticsearch can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user can submit a specially crafted query that causes excessive resource consumption while the request is processed, which may render the affected node unavailable.
CVE-2026-56149 1 Elastic 1 Elasticsearch 2026-07-02 N/A 4.9 MEDIUM
Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can lead to a denial of service via Excessive Allocation (CAPEC-130). A user with elevated privileges can submit a specially crafted machine learning request that causes excessive memory consumption, which may render the affected node unavailable.
CVE-2026-56151 1 Elastic 1 Kibana 2026-07-02 N/A 6.5 MEDIUM
Improper Input Validation (CWE-20) in Kibana can lead to a denial of service via Input Data Manipulation (CAPEC-153). An authenticated user can submit a specially crafted Fleet policy input that is not correctly validated, which can render Fleet agent, server, and policy management functionality unavailable.
CVE-2026-49090 1 Elastic 1 Elasticsearch 2026-07-02 N/A 6.5 MEDIUM
Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user can submit a specially crafted bulk request that causes sustained high CPU consumption, which can render the affected node unable to process requests.
CVE-2026-4498 1 Elastic 1 Kibana 2026-06-17 N/A 7.7 HIGH
Execution with Unnecessary Privileges (CWE-250) in Kibana’s Fleet plugin debug route handlers can lead reading index data beyond their direct Elasticsearch RBAC scope via Privilege Abuse (CAPEC-122). This requires an authenticated Kibana user with Fleet sub-feature privileges (such as agents, agent policies, and settings management).
CVE-2026-49095 1 Elastic 1 Kibana 2026-06-17 N/A 6.5 MEDIUM
Improper Input Validation (CWE-20) in the Kibana Fleet agent policy management feature can lead to privilege escalation. An authenticated user with Fleet management privileges can manipulate agent policy configuration by injecting values into a configuration override mechanism that is not adequately validated. An attacker can cause Elastic Agents to be issued API keys with elevated Elasticsearch privileges, potentially granting unauthorized read and write access to sensitive Elasticsearch security indices beyond what is intended for the Fleet management role.
CVE-2026-49094 1 Elastic 1 Kibana 2026-06-17 N/A 6.5 MEDIUM
Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with viewer-level access can submit a request containing an oversized input value to an analytics collections management endpoint. Kibana will consume excessive CPU and memory resources while processing the request. This results in Kibana becoming unavailable to all users until the service is manually recovered.
CVE-2026-49093 1 Elastic 1 Kibana 2026-06-17 N/A 6.3 MEDIUM
Server-Side Request Forgery (CWE-918) in Kibana can allow an authenticated user with connector management privileges to bypass the operator-configured connector allowlist, causing the Kibana server to issue outbound requests to destinations the egress controls were intended to block.
CVE-2026-42401 1 Elastic 1 Kibana 2026-06-17 N/A 4.1 MEDIUM
Improper Neutralization of Input During Web Page Generation (CWE-79) in Kibana can lead to stored HTML injection. A user with write access to an Elasticsearch index could persist crafted markup which, when subsequently rendered through an affected Kibana view by another user, was not sufficiently sanitized. Successful exploitation could result in unauthorized UI manipulation and outbound network requests issued from the viewing user's browser session.
CVE-2026-42400 1 Elastic 1 Kibana 2026-06-17 N/A 6.5 MEDIUM
Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user can send a specially crafted compressed request payload that is processed prior to authorization checks, causing excessive memory and CPU resource consumption that can result in a Kibana instance becoming unresponsive or crashing.
CVE-2026-42399 1 Elastic 1 Kibana 2026-06-17 N/A 6.5 MEDIUM
Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated low-privileged user can cause Kibana to consume exponentially increasing amounts of memory by submitting a specially crafted Timelion visualization expression containing deeply chained function calls. The resulting data structure grows without bound, exhausting available memory and causing the Kibana service to crash and become unavailable to all users.
CVE-2026-42398 1 Elastic 1 Kibana 2026-06-17 N/A 7.7 HIGH
Server-Side Request Forgery (CWE-918) in Kibana allows authenticated users with connector management privileges to bypass the operator-configured connection allowlist. By configuring a Webhook connector with a crafted target, an attacker can cause Kibana to issue outbound requests to destinations that the egress restriction controls were intended to block.
CVE-2026-33467 1 Elastic 1 Elastic Package Registry 2026-06-17 N/A 5.9 MEDIUM
Improper Verification of Cryptographic Signature (CWE-347) in Elastic Package Registry could allow an attacker positioned to intercept network traffic, or to otherwise influence the contents served to a self-hosted registry, to substitute a tampered package without the integrity check failing closed.
CVE-2026-33466 1 Elastic 1 Logstash 2026-06-17 N/A 8.1 HIGH
Improper Limitation of a Pathname to a Restricted Directory (CWE-22) in Logstash can lead to arbitrary file write and potentially remote code execution via Relative Path Traversal (CAPEC-139). The archive extraction utilities used by Logstash do not properly validate file paths within compressed archives. An attacker who can serve a specially crafted archive to Logstash through a compromised or attacker-controlled update endpoint can write arbitrary files to the host filesystem with the privileges of the Logstash process. In certain configurations where automatic pipeline reloading is enabled, this can be escalated to remote code execution.
CVE-2026-33464 1 Elastic 1 Kibana 2026-06-17 N/A 6.5 MEDIUM
Uncontrolled Resource Consumption (CWE-400) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user holding a low-privileged role can submit a specially crafted, oversized payload to an internal Kibana API, causing the Kibana process to exhaust available resources and become unresponsive to all users until the service recovers or is restarted.
