Kibana Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper neutralization of input during web page generation ('Cross-site Scripting') (CWE-79) allows an authenticated user to embed a malicious script in content that will be served to web browsers causing cross-site scripting (XSS) (CAPEC-63) via a method in Vega bypassing a previous Vega XSS mitigation.

Filebeat Improper Validation of Specified Index, Position, or Offset in Input

Improper Validation of Specified Index, Position, or Offset in Input (CWE-1285) in Filebeat Syslog parser and the Libbeat Dissect processor can allow a user to trigger a Buffer Overflow (CAPEC-100) and cause a denial of service (panic/crash) of the Filebeat process via either a malformed Syslog message or a malicious tokenizer pattern in the Dissect configuration.

Elasticsearch Allocation of Resources Without Limits or Throttling

Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can allow a low-privileged authenticated user to cause Excessive Allocation (CAPEC-130) causing a persistent denial of service (OOM crash) via submission of oversized user settings data.

Elasticsearch Allocation of Resources Without Limits or Throttling

Allocation of Resources Without Limits or Throttling (CWE-770) in Elasticsearch can allow an authenticated user with snapshot restore privileges to cause Excessive Allocation (CAPEC-130) of memory and a denial of service (DoS) via crafted HTTP request.

Allocation of resources without limits or throttling (CWE-770) allows an unauthenticated remote attacker to cause excessive allocation (CAPEC-130) of memory and CPU via the integration of malicious IPv4 fragments, leading to a degradation in Packetbeat.

Packetbeat Out-of-bounds Read

Out-of-bounds read (CWE-125) allows an unauthenticated remote attacker to perform a buffer overflow (CAPEC-100) via the NFS protocol dissector, leading to a denial-of-service (DoS) through a reliable process crash when handling truncated XDR-encoded RPC messages.

Packetbeat Improper Bounds Check

Improper Bounds Check (CWE-787) in Packetbeat can allow a remote unauthenticated attacker to exploit a Buffer Overflow (CAPEC-100) and reliably crash the application or cause significant resource exhaustion via a single crafted UDP packet with an invalid fragment sequence number.

Elasticsearch Insertion of sensitive information in log file

Insertion of sensitive information in log file in Elasticsearch can lead to loss of confidentiality under specific preconditions when auditing requests to the reindex API https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-reindex

Kibana Cross-site Scripting via the Integration Package Upload Functionality

Improper neutralization of input during web page generation ('Cross-site Scripting') (CWE-79) allows an authenticated user to render HTML tags within a user’s browser via the integration package upload functionality. This issue is related to ESA-2025-17 (CVE-2025-25018) bypassing that fix to achieve HTML injection.

Kibana Origin Validation Error

Origin Validation Error in Kibana can lead to Server-Side Request Forgery via a forged Origin HTTP header processed by the Observability AI Assistant.

kibana: Arbitrary code execution flaw in the Timelion visualizer

Kibana versions before 5.6.15 and 6.6.1 contain an arbitrary code execution flaw in the Timelion visualizer. An attacker with access to the Timelion application could send a request that will attempt to execute javascript code. This could possibly lead to an attacker executing arbitrary commands with permissions of the Kibana process on the host system.

Kibana Cross-Site Scripting (XSS)

Improper Neutralization of Input During Web Page Generation in Kibana can lead to Stored XSS via case file upload.

Kibana Stored Cross-Site Scripting (XSS)

Improper Neutralization of Input During Web Page Generation in Kibana can lead to Cross-Site Scripting (XSS)

Elasticsearch Uncontrolled Resource Consumption vulnerability

Uncontrolled Resource Consumption in Elasticsearch while evaluating specifically crafted search templates with Mustache functions can lead to Denial of Service by causing the Elasticsearch node to crash.

Kibana Unrestricted Upload of File

Unrestricted file upload in Kibana allows an authenticated attacker to compromise software integrity by uploading a crafted malicious file due to insufficient server-side validation.

An issue was discovered in Elasticsearch, where a large recursion using the Well-KnownText formatted string with nested GeometryCollection objects could cause a stackoverflow.

Elastic Agent / Elastic Endpoint Security local API key disclosure

Exposure of sensitive information to local unauthorized actors in Elastic Agent and Elastic Security Endpoint can lead to loss of confidentiality and impersonation of Endpoint to the Elastic Stack. This issue was identified by Elastic engineers and Elastic has no indication that it is known or has been exploited by malicious actors.

Kibana Unrestricted Upload of File with Dangerous Type Can Lead to XSS

Unrestricted upload of a file with dangerous type in Kibana can lead to arbitrary JavaScript execution in a victim’s browser (XSS) via crafted HTML and JavaScript files. The attacker must have access to the Synthetics app AND/OR have access to write to the synthetics indices.

Elastic Agent Inclusion of Functionality from Untrusted Control Sphere

Inclusion of functionality from an untrusted control sphere in Elastic Agent subprocess, osqueryd, allows local attackers to execute arbitrary code via parameter injection. An attacker requires local access and the ability to modify osqueryd configurations.

Kibana arbitrary code execution via YAML deserialization

A deserialization issue in Kibana can lead to arbitrary code execution when Kibana attempts to parse a YAML document containing a crafted payload. A successful attack requires a malicious user to have a combination of both specific Elasticsearch indices privileges https://www.elastic.co/guide/en/elasticsearch/reference/current/defining-roles.html#roles-indices-priv  and Kibana privileges https://www.elastic.co/guide/en/fleet/current/fleet-roles-and-privileges.html  assigned to them. The following Elasticsearch indices permissions are required * write privilege on the system indices .kibana_ingest* * The allow_restricted_indices flag is set to true Any of the following Kibana privileges are additionally required * Under Fleet the All privilege is granted * Under Integration the Read or All privilege is granted * Access to the fleet-setup privilege is gained through the Fleet Server’s service account token
