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.

Improper Authorization (CWE-285) in Kibana can lead to privilege escalation (CAPEC-233) by allowing an authenticated user to change a document's sharing type to "global," even though they do not have permission to do so, making it visible to everyone in the space via a crafted a HTTP request.

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) in Kibana can allow a low-privileged authenticated user to cause Excessive Allocation (CAPEC-130) of computing resources and a denial of service (DoS) of the Kibana process via a crafted HTTP request.

Improper neutralization of input during web page generation ('Cross-site Scripting') (CWE-79) allows an unauthenticated user to embed a malicious script in content that will be served to web browsers causing cross-site scripting (XSS) (CAPEC-63) via a vulnerability a function handler in the Vega AST evaluator.

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.

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.

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.

CVE-2025-68381 is a medium severity vulnerability in Elastic Packetbeat affecting versions 7.0.0 through 9.2.0. It involves an out-of-bounds write (CWE-787) due to improper bounds checking, which can be triggered remotely without authentication by sending a crafted UDP packet with an invalid fragment sequence number. Exploitation can cause a buffer overflow leading to application crashes or significant resource exhaustion, impacting availability. The vulnerability does not affect confidentiality or integrity and requires network access with no user interaction. No known exploits are currently in the wild. European organizations using Packetbeat for network monitoring could face service disruptions if targeted.

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.

Improper Authentication in Elasticsearch PKI realm can lead to user impersonation via specially crafted client certificates. A malicious actor would need to have such a crafted client certificate signed by a legitimate, trusted Certificate Authority.

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.

Missing Authorization vulnerability in Elastic Email Elastic Email Sender elastic-email-sender allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Elastic Email Sender: from n/a through <= 1.2.20.

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

Improper Authorization in Elastic Cloud Enterprise can lead to Privilege Escalation where the built-in readonly user can call APIs that should not be allowed. The list of APIs that are affected by this issue is: post:/platform/configuration/security/service-accounts delete:/platform/configuration/security/service-accounts/{user_id} patch:/platform/configuration/security/service-accounts/{user_id} post:/platform/configuration/security/service-accounts/{user_id}/keys delete:/platform/configuration/security/service-accounts/{user_id}/keys/{api_key_id} patch:/user post:/users post:/users/auth/keys delete:/users/auth/keys delete:/users/auth/keys/_all delete:/users/auth/keys/{api_key_id} delete:/users/{user_id}/auth/keys delete:/users/{user_id}/auth/keys/{api_key_id} delete:/users/{user_name} patch:/users/{user_name}

Improper preservation of permissions in Elastic Defend on Windows hosts can lead to arbitrary files on the system being deleted by the Defend service running as SYSTEM. In some cases, this could result in local privilege escalation.

Improper neutralization of special elements used in a template engine in Elastic Cloud Enterprise (ECE) can lead to a malicious actor with Admin access exfiltrating sensitive information and issuing commands via a specially crafted string where Jinjava variables are evaluated.

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