CVE-2026-49089 (GCVE-0-2026-49089)

Vulnerability from cvelistv5 – Published: 2026-08-13 19:08 – Updated: 2026-08-13 20:35

Title

Allocation of Resources Without Limits or Throttling in Kibana Leading to Denial of Service

Summary

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). A query expression accepted by a connector reporting operation was processed without any limit on its size, and an oversized expression caused the Kibana process to spend an unbounded amount of time evaluating it. An authenticated user with read-only privileges was able to send a single request that left Kibana unable to serve any user until the process was restarted.

Severity

6.5 (Medium)

CVE-2026-72629 (GCVE-0-2026-72629)

Vulnerability from cvelistv5 – Published: 2026-08-13 19:13 – Updated: 2026-08-13 20:27

Title

Authorization Bypass Through User-Controlled Key in Kibana Leading to Cross-Space Access to Machine Learning Trained Models

Summary

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized cross-space access via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). The result is disclosure of inference output from a trained model in a different space that the user is not authorized to list, read, or use, which exposes the behavior of a model. The same pattern also reached the deployment stop and deployment update operations, allowing an active trained model deployment in another space to be stopped or to have its allocated resources altered.

Severity

7.1 (High)

CVE-2026-72630 (GCVE-0-2026-72630)

Title

Incorrect Authorization in Kibana Fleet Leading to Privilege Escalation

Summary

Incorrect Authorization (CWE-863) in Kibana Fleet can lead to privilege escalation via Privilege Abuse (CAPEC-122). Fleet restricts some callers to managing integration policies for one specific integration. When an existing integration policy was updated, that restriction was evaluated against the integration recorded on the stored policy rather than against the replacement integration supplied with the update. An authenticated user holding only the Elastic Defend endpoint policy management privilege was therefore able to convert an endpoint policy they administer into a policy for a different integration, and to supply that integration's configuration at the same time.

Severity

7.1 (High)

Title

Improper Privilege Management in Kibana Fleet Leading to Over-Scoped Elastic Agent API Keys

Summary

Improper Privilege Management (CWE-269) in Kibana Fleet can lead to privilege escalation via Privilege Escalation (CAPEC-233). An integration policy may optionally declare extra data streams that the integration writes to, which Fleet adds to the Elasticsearch API key issued to Elastic Agents enrolled in the corresponding agent policy. The resulting key allows new documents to be inserted and index mappings to be extended for specific indices. The key does not allow reading, updating, or deleting existing documents

Title

Observable Discrepancy in Kibana Fleet Leading to Disclosure of Elastic Agent Elasticsearch API Keys

Summary

Observable Discrepancy (CWE-203) in Kibana Fleet can lead to information disclosure via Excavation (CAPEC-116). Fleet removes the Elasticsearch API key value of an enrolled Elastic Agent from the responses of its agent listing capability, but that capability accepted caller-supplied filter expressions over the stored field that holds the value, and evaluated them with Kibana's own internal Elasticsearch privileges rather than the caller's. Because the number of matching agents is reported back to the caller, the difference between a matching and a non-matching filter formed a side channel from which the full API key value could be reconstructed one character at a time with a short sequence of requests.

Severity

7.1 (High)

Title

Incorrect Authorization in Kibana Agent Builder Leading to Disclosure and Tampering of Private Agents

Summary

Kibana Agent Builder determines whether a caller owns a private agent by comparing a stable user identifier when one is recorded, and falling back to a comparison of the username when it is not. A username is not unique across Elasticsearch authentication realms, so two distinct principals that share a username in different realms are treated as the same owner. This discloses the configuration and instructions of an agent the caller does not own, and allows that agent to be altered or removed.

CVE-2026-72650 (GCVE-0-2026-72650)

Vulnerability from cvelistv5 – Published: 2026-08-13 19:13 – Updated: 2026-08-13 20:30

Title

Authorization Bypass Through User-Controlled Key in Kibana Leading to Information Disclosure

Summary

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user who is authorized to read alerting rules in a single Kibana space could retrieve alerting rule execution telemetry that belongs to spaces the user is not authorized to access. The disclosed telemetry includes rule identifiers, rule names, space identifiers, execution outcomes, timestamps, and execution counters.

Severity

4.3 (Medium)

CVE-2026-72651 (GCVE-0-2026-72651)

Vulnerability from cvelistv5 – Published: 2026-08-13 19:13 – Updated: 2026-08-13 20:30

Title

Allocation of Resources Without Limits or Throttling in Kibana Leading to Denial of Service

Summary

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user with read-only privileges to the alerting feature could submit a specially crafted, malformed payload that causes the Kibana process to consume excessive resources. A single request is sufficient to leave Kibana unable to serve requests for all users until the process is restarted.

Severity

6.5 (Medium)

Vulnerability from cvelistv5 – Published: 2026-08-13 19:13 – Updated: 2026-08-13 20:29

Title

Allocation of Resources Without Limits or Throttling in Kibana Leading to Denial of Service

Summary

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user who is authorized to manage maintenance windows could submit a specially crafted, malformed payload that causes the Kibana process to consume excessive resources. Kibana becomes unresponsive for all users and does not recover without manual intervention.
