Denial of service in Kibana's analytics collections management endpoint allows any authenticated user with viewer-level access to render the service completely unavailable. By submitting a request containing an oversized input value, the attacker causes Kibana to consume excessive CPU and memory, crashing the service for all users and requiring manual intervention to restore. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the low privilege bar - viewer access only - significantly elevates real-world risk in multi-tenant or SaaS Elastic deployments.
Privilege escalation in Elastic Kibana's Fleet agent policy management feature allows authenticated Fleet administrators to inject unvalidated values into a configuration override mechanism, causing Elastic Agents to be provisioned with API keys carrying elevated Elasticsearch privileges. Successful exploitation yields unauthorized read/write access to sensitive Elasticsearch security indices beyond the Fleet role's intended scope. No public exploit identified at time of analysis, and CISA KEV does not list this issue.
Denial of service in Elastic Kibana allows an authenticated low-privileged user to crash the Kibana service and deny access to all users by submitting a maliciously crafted Timelion visualization expression. The Timelion expression parser fails to bound the depth of chained function call processing, causing the resulting data structure to grow exponentially and exhaust available server memory. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the low attack complexity and minimal privilege requirements make it an accessible attack surface for any credentialed Kibana user.
Denial of service in Kibana allows any authenticated user to crash or render unresponsive a Kibana instance by sending a specially crafted compressed HTTP request payload. The root cause is an architectural ordering flaw: compressed payloads are decompressed and processed before authorization checks are applied, enabling resource exhaustion (CWE-400, CAPEC-130 Excessive Allocation) at minimal privilege cost. No public exploit identified at time of analysis and no CISA KEV listing, but the low attack complexity and broad authentication base (any valid Kibana login) make this a meaningful availability risk for multi-tenant or internet-exposed deployments.
Stored HTML injection in Kibana allows a low-privileged authenticated user with write access to an Elasticsearch index to persist crafted markup that is insufficiently sanitized when rendered in an affected Kibana view. When a second user opens the compromised view, their browser processes the unsanitized content, enabling unauthorized manipulation of the Kibana UI and issuing outbound network requests from the victim's browser session. No public exploit identified at time of analysis, no CISA KEV listing, and EPSS data was not provided in source intelligence.
Expired access tokens in Kibana remain exploitable due to a logic error in expiration timestamp validation (CWE-672), allowing an unauthenticated actor who possesses an expired token to retrieve content it was originally scoped to access. The flaw affects all tracked Kibana versions per the NVD CPE wildcard, and Elastic has issued a security advisory (ESA-2026-33) with patch versions. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog at time of analysis. The CVSS 5.3 Medium score reflects constrained confidentiality impact with no integrity or availability consequence.
Denial of service in Kibana allows any authenticated low-privileged user to render the Kibana service unresponsive for all users by submitting an oversized, specially crafted payload to an internal API endpoint. The CVSS vector (AV:N/AC:L/PR:L/UI:N/A:H) confirms straightforward network exploitation requiring only valid low-privileged credentials with no user interaction - a low barrier for any insider or compromised account. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the low complexity and authenticated-but-low-privilege condition makes this a realistic risk in shared Kibana deployments.
Blind Server-Side Request Forgery in FlaskBB's avatar URL handling allows any authenticated user to force the server to issue arbitrary HTTP GET requests to internal network endpoints, including cloud instance metadata services (AWS IMDSv1 at 169.254.169.254, GCP, Azure equivalents). All versions up to and including 2.2.0 of the pip-distributed FlaskBB package are affected, with no vendor-released patch available at time of analysis. A proof-of-concept is publicly available via the GitHub Security Advisory, and three distinct exploitation channels have been demonstrated: direct credential exfiltration from cloud metadata services, internal port scanning via differential error responses, and triggering of internal APIs (Elasticsearch, etcd, Consul, CI/CD webhooks).
Authorization bypass in phpMyFAQ versions before 4.1.2 allows authenticated frontend users to access admin-only API endpoints and retrieve sensitive backend configuration data. The vulnerability stems from admin-api routes checking only login status (isLoggedIn) without verifying administrative privileges, enabling any valid user account to query dashboard versions, LDAP configuration details, Elasticsearch statistics, and health-check data. While this is an information disclosure issue rather than direct write access, it exposes internal infrastructure details useful for reconnaissance. The low CVSS score (4.3) reflects limited confidentiality impact, but defenders should prioritize remediation in environments where backend configuration exposure aids broader attack campaigns. Vendor patch available in version 4.1.2.
Server-Side Request Forgery in @utcp/http <= 1.1.1 allows remote attackers to redirect tool invocations to internal services via malicious OpenAPI specs. An attacker hosting a malicious OpenAPI specification on a legitimate HTTPS endpoint can declare internal server URLs (e.g., http://127.0.0.1:9090 or http://169.254.169.254) in the servers array; the OpenApiConverter blindly trusts these URLs without revalidation during tool invocation, enabling access to cloud metadata endpoints, internal databases, and loopback services. Additionally, a prefix-bypass in hostname validation (startsWith check) allows URLs like http://localhost.evil.com to bypass discovery-time restrictions. Patch version 1.1.2 is available.
Apache Airflow Elasticsearch provider writes embedded credentials from the `[elasticsearch] host` configuration URL directly into task logs, allowing any user with task-log read permissions to harvest backend authentication credentials. The vulnerability affects Apache Airflow Providers Elasticsearch versions before 6.5.3 and has been patched by stripping userinfo from the host URL before logging. EPSS exploitation probability is low (0.02%, percentile 4%), indicating limited real-world exploitation despite the sensitive nature of credential exposure.
Server-Side Request Forgery in utcp-http allows remote attackers to access internal cloud metadata endpoints and firewalled services by hosting a malicious OpenAPI specification on a legitimate HTTPS endpoint that declares internal server URLs, which are then blindly trusted during tool invocation without revalidation. The vulnerability affects utcp-http versions 1.1.1 and earlier, where `call_tool()` and `call_tool_streaming()` reuse previously resolved URLs from OpenAPI specs without re-checking security constraints, combined with a string-prefix bypass (`localhost.evil.com` bypassing `startswith` checks). This is a blind SSRF that exposes cloud metadata (AWS/GCP credentials from 169.254.169.254), internal services like Elasticsearch and Redis, and enables exfiltration via LLM responses when combined with prompt injection. No public exploit code or active exploitation is currently identified, but the vulnerability requires only network-level access and user interaction (convincing an LLM agent to register a malicious tool).
Cryptographic signature verification bypass in Elastic Package Registry versions 0.1.0 through 1.37.0 allows an adversary-in-the-middle, or an attacker with influence over a self-hosted registry's served content, to substitute tampered packages that are accepted without triggering integrity check failures. The flaw (CWE-347) undermines supply-chain integrity for organizations running self-hosted registry instances. No active exploitation is confirmed (SSVC: exploitation none; EPSS 0.02%), but the high integrity impact and zero-privilege-required vector make patching to 1.38.0 a priority for self-hosted deployments.
Spring Boot's Elasticsearch auto-configuration omits hostname verification when an SSL bundle is used, opening TLS connections to the Elasticsearch server to man-in-the-middle interception by an attacker on the adjacent network. Affected versions are 4.0.0 through 4.0.5; only deployments explicitly configured with an SSL bundle are exposed. No active exploitation is confirmed (absent from CISA KEV, EPSS 0.01% at the 3rd percentile), and VMware has released a fix in version 4.0.6.
Stored cross-site scripting (XSS) in Mahara before 25.04.2 and 24.04.11 allows unauthenticated remote attackers to inject malicious JavaScript via unsanitized search query parameters in the 'search site' feature when the Elasticsearch7 search plugin is enabled. The vulnerability has a CVSS score of 6.1 (moderate) with network attack vector and user interaction required (clicking a crafted search link), resulting in partial confidentiality and integrity impact. No active exploitation has been confirmed by CISA KEV, and no public exploit code is documented at the time of analysis.
Denial of service in Kibana's automatic import feature allows authenticated users to trigger uncontrolled resource consumption by submitting specially crafted requests with excessively large input values. When multiple such requests are sent concurrently, backend services become unstable, resulting in service disruption across all users. CVSS 6.5 (medium severity) reflects the authenticated attack requirement and high availability impact without confidentiality or integrity compromise.
Kibana's Fleet agent management endpoint fails to enforce space-scoped access controls, allowing authenticated users with Fleet privileges in one space to retrieve sensitive Fleet Server policy details from unauthorized spaces including policy names, operational identifiers, and infrastructure linkage information. The vulnerability affects Kibana across multiple versions and requires valid user authentication with Fleet agent management permissions, resulting in cross-space information disclosure without the ability to modify data.
Authorization bypass in Elastic Kibana allows authenticated users with limited Fleet privileges to retrieve sensitive configuration data including private keys and authentication tokens through an internal API endpoint. The vulnerability affects network-accessible instances and bypasses intended privilege boundaries by returning full configuration objects without proper authorization checks. CVSS score of 7.7 reflects high confidentiality impact with scope change. No public exploit identified at time of analysis, though the attack vector is straightforward for authenticated users.
Local privilege escalation in Dell Elastic Cloud Storage (≤3.8.1.7) and ObjectScale (<4.1.0.3, =4.2.0.0) allows authenticated users with low privileges to extract credentials from log files and escalate to compromised account privileges. CVSS 7.8 (High). No public exploit identified at time of analysis. EPSS data not available, but local access requirement and low attack complexity suggest moderate exploitation likelihood in multi-tenant or shared administrative environments.
Server-side request forgery (SSRF) in Dataease SQLBot up to version 1.6.0 allows high-privileged remote attackers to manipulate the 'address' argument in the Elasticsearch Handler component (get_es_data_by_http function), enabling unauthorized HTTP requests to internal or external systems. The vulnerability has publicly available exploit code and vendor-released patch version 1.7.0 addresses the issue.
Search Guard FLX versions 1.0.0 through 4.0.1 leak user credentials into audit logs when users authenticate through Kibana, exposing plaintext authentication material to any system administrator or user with log access. The vulnerability requires high-privilege access to exploit and affects only confidentiality, but the presence of credentials in audit logs creates a persistent information disclosure risk that persists across backup and archival systems.
Metricbeat's Prometheus remote_write HTTP handler is vulnerable to denial of service through excessive memory allocation when processing specially crafted requests from authenticated network-adjacent attackers. An attacker with local privileges can trigger unbounded memory allocation to exhaust system resources and crash the service. No patch is currently available for this vulnerability.
A Denial of Service vulnerability exists in Kibana's Timelion visualization plugin that allows authenticated users to trigger excessive memory allocation through improper validation of specially crafted Timelion expressions. An attacker with valid Kibana credentials can overwrite internal series data properties with excessively large quantity values, causing the application to exhaust system resources and become unavailable. This is a network-accessible vulnerability requiring low privileges with a CVSS score of 6.5 and documented as a confirmed denial-of-service attack vector affecting multiple active Kibana versions.
Kibana's Detection Rule Management lacks proper authorization controls, allowing authenticated users with rule management privileges to configure unauthorized endpoint response actions including host isolation and process termination. An attacker with these privileges could exploit this missing access control to execute sensitive endpoint operations beyond their intended scope. No patch is currently available for this medium-severity vulnerability affecting Elastic products.
Packetbeat contains an improper array index validation vulnerability (CWE-129) in its protocol parser components that allows attackers to trigger out-of-bounds read operations through specially crafted network packets. Affected versions include Packetbeat 8.0.0 through 8.19.10 and 9.0.0 through 9.2.4, with the vulnerability requiring network-level access or traffic control to the monitored interface. An attacker exploiting this flaw can cause denial of service through application crashes or resource exhaustion; while the CVSS score of 5.7 indicates moderate severity and there is no indication of widespread active exploitation in public KEV databases, the patch availability through Elastic's security update (ESA-2026-11) released in version 8.19.11 and 9.2.5 suggests this is a confirmed and prioritized vulnerability worthy of timely remediation.
An unauthenticated Server-Side Request Forgery (SSRF) and Local File Read vulnerability exists in the Admidio SSO metadata fetch endpoint, which accepts arbitrary URLs via GET parameter and passes them directly to file_get_contents() after validating only with PHP's FILTER_VALIDATE_URL-a format checker that does not block dangerous URI schemes. An authenticated administrator can exploit this to read arbitrary local files (including database credentials from config.php), probe internal network services, or fetch cloud instance metadata (such as AWS IAM credentials from 169.254.169.254). A proof-of-concept demonstrating all attack vectors has been published; CVSS 6.8 reflects high confidentiality impact but is mitigated by the requirement for administrator privileges.
CRLF injection in undici's HTTP upgrade handling allows authenticated attackers to inject arbitrary headers and perform request smuggling attacks against backend services like Redis and Elasticsearch when user input is passed unsanitized to the upgrade option. The vulnerability stems from insufficient validation of the upgrade parameter before writing to the socket, enabling attackers to terminate HTTP requests prematurely and route malicious data to non-HTTP protocols. This requires prior authentication and user interaction, with no patch currently available.
Kibana's Timelion component is vulnerable to denial of service through uncontrolled resource consumption when processing malicious input data, affecting authenticated users with network access to the application. An attacker with valid credentials can manipulate input to exhaust system resources and render the service unavailable. No patch is currently available for this vulnerability.

An unauthenticated attacker on the network can exploit this to crash monitoring services without user interaction. No patch is currently available.
A low-privileged authenticated user can cause a persistent denial of service in Elasticsearch by submitting oversized user settings data, leading to an out-of-memory crash. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) and affects versions prior to 8.19.9, 9.1.9, and 9.2.3. No public exploit code has been identified, and EPSS is low at 0.32% (23rd percentile).
Authentication bypass in the Elasticsearch PKI realm lets a remote, unauthenticated attacker who presents a specially crafted X.509 client certificate - signed by a Certificate Authority the cluster already trusts - be resolved to another user's identity, granting that user's read and write privileges (CVSS 3.1:7.4, C:H/I:H/A:N). Exploitation is gated by two prerequisites: the PKI realm must be explicitly enabled and configured for client-certificate authentication (it is not a default mode), and the attacker must hold a certificate issued by a CA in the cluster's trusted set, so realistic exposure is limited to deployments whose trusted CA issues certificates beyond a small high-trust population. No public exploit code has been identified at time of analysis, and the issue is not listed in CISA KEV; Elastic has published a fix in the ESA-2025-27 advisory covering Elasticsearch 8.19.8, 9.1.8, and 9.2.2.

Server-side template injection (SSTI) in Elastic Cloud Enterprise (ECE) allows an authenticated Administrator to execute arbitrary Jinjava expressions, leading to sensitive information disclosure and command execution. The vulnerability affects ECE versions prior to 3.8.2 and 4.0.2, and requires the attacker to already possess admin privileges; no public exploit code has been identified at time of analysis. Elastic has assigned a CVSS score of 7.2 (High) with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H.
Information disclosure in Elasticsearch audit logs allows an authenticated low-privilege attacker with adjacent network access and read access to the audit log to obtain sensitive data when audit logging is enabled and configured to log reindex API requests. The issue is non-default (auditing must be explicitly turned on), requires high attack complexity per our assessment, and affects confidentiality only with no integrity or availability impact. No public exploit identified at time of analysis, and EPSS is low at 0.25% (15th percentile); the NVD base score is 5.7 but our assessment suggests a modest-priority issue rather than a high-severity emergency.
Stored cross-site scripting in Elastic Kibana lets an authenticated user who can create or modify persistent content, such as saved objects, dashboards, or similar rendered fields, inject a payload that later executes in the browser of any other user viewing that content. Exploitation requires a valid low-privileged Kibana account plus a second victim (often a higher-privileged operator) actively opening the affected page, and impact is limited to low confidentiality and integrity within the victim's browser session. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis; EPSS is low at 0.23% (13th percentile), so this is a routine-patching-priority moderate-severity issue rather than an emergency.
Cross-site scripting (XSS) in Elastic Kibana allows remote unauthenticated attackers to inject malicious scripts into web pages, which execute when a logged-in user opens a crafted link or views a compromised page. Affected versions are all releases prior to the fixed versions 8.18.8, 8.19.4, 9.0.7, and 9.1.4. No public exploit code or active exploitation is known, and with a low EPSS score (0.27%), this is assessed as a moderate, not a priority, issue.
Authenticated users holding only read-only API access in Nagios Log Server versions prior to 2024R1.3.2 can stop the underlying Elasticsearch service by calling the system stop endpoint with the elasticsearch subsystem parameter, degrading availability of the log ingestion, indexing, and search stack. The vulnerability is an incorrect authorization flaw (CWE-863) rated CVSS 6.5 with a PR:L vector, meaning the attacker must already possess valid credentials - no unauthenticated path exists - and impact is limited to availability with no data disclosure or modification. Publicly available exploit code exists (a GitHub proof-of-concept), and EPSS places the issue at roughly 2.77% (86th percentile), but there is no confirmation of active exploitation in CISA KEV; a vendor fix is available in 2024R1.3.2.
Stored cross-site scripting in Elastic Kibana's Cases file-upload feature lets an authenticated user with case attachment privileges plant a crafted file whose payload executes as script in a different user's browser when that case is opened. Elastic scores it CVSS 5.4 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N), meaning exploitation needs a valid low-privileged account plus victim interaction, and the impact is limited to the viewing user's browser session and Kibana privilege level. No public exploit identified at time of analysis, it is not in CISA KEV, EPSS is 0.24% (14th percentile), and vendor-released fixes exist in 8.18.8, 8.19.5, 9.0.8, and 9.1.5.

Denial of service in Kibana's analytics collections management endpoint allows any authenticated user with viewer-level access to render the service completely unavailable. By submitting a request containing an oversized input value, the attacker causes Kibana to consume excessive CPU and memory, crashing the service for all users and requiring manual intervention to restore. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, but the low privilege bar - viewer access only - significantly elevates real-world risk in multi-tenant or SaaS Elastic deployments.
Privilege escalation in Elastic Kibana's Fleet agent policy management feature allows authenticated Fleet administrators to inject unvalidated values into a configuration override mechanism, causing Elastic Agents to be provisioned with API keys carrying elevated Elasticsearch privileges. Successful exploitation yields unauthorized read/write access to sensitive Elasticsearch security indices beyond the Fleet role's intended scope. No public exploit identified at time of analysis, and CISA KEV does not list this issue.
Denial of service in Elastic Kibana allows an authenticated low-privileged user to crash the Kibana service and deny access to all users by submitting a maliciously crafted Timelion visualization expression. The Timelion expression parser fails to bound the depth of chained function call processing, causing the resulting data structure to grow exponentially and exhaust available server memory. No public exploit has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; however, the low attack complexity and minimal privilege requirements make it an accessible attack surface for any credentialed Kibana user.
Denial of service in Kibana allows any authenticated user to crash or render unresponsive a Kibana instance by sending a specially crafted compressed HTTP request payload. The root cause is an architectural ordering flaw: compressed payloads are decompressed and processed before authorization checks are applied, enabling resource exhaustion (CWE-400, CAPEC-130 Excessive Allocation) at minimal privilege cost. No public exploit identified at time of analysis and no CISA KEV listing, but the low attack complexity and broad authentication base (any valid Kibana login) make this a meaningful availability risk for multi-tenant or internet-exposed deployments.
Stored HTML injection in Kibana allows a low-privileged authenticated user with write access to an Elasticsearch index to persist crafted markup that is insufficiently sanitized when rendered in an affected Kibana view. When a second user opens the compromised view, their browser processes the unsanitized content, enabling unauthorized manipulation of the Kibana UI and issuing outbound network requests from the victim's browser session. No public exploit identified at time of analysis, no CISA KEV listing, and EPSS data was not provided in source intelligence.
Expired access tokens in Kibana remain exploitable due to a logic error in expiration timestamp validation (CWE-672), allowing an unauthenticated actor who possesses an expired token to retrieve content it was originally scoped to access. The flaw affects all tracked Kibana versions per the NVD CPE wildcard, and Elastic has issued a security advisory (ESA-2026-33) with patch versions. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog at time of analysis. The CVSS 5.3 Medium score reflects constrained confidentiality impact with no integrity or availability consequence.
Denial of service in Kibana allows any authenticated low-privileged user to render the Kibana service unresponsive for all users by submitting an oversized, specially crafted payload to an internal API endpoint. The CVSS vector (AV:N/AC:L/PR:L/UI:N/A:H) confirms straightforward network exploitation requiring only valid low-privileged credentials with no user interaction - a low barrier for any insider or compromised account. No public exploit code and no CISA KEV listing have been identified at time of analysis, though the low complexity and authenticated-but-low-privilege condition makes this a realistic risk in shared Kibana deployments.
Blind Server-Side Request Forgery in FlaskBB's avatar URL handling allows any authenticated user to force the server to issue arbitrary HTTP GET requests to internal network endpoints, including cloud instance metadata services (AWS IMDSv1 at 169.254.169.254, GCP, Azure equivalents). All versions up to and including 2.2.0 of the pip-distributed FlaskBB package are affected, with no vendor-released patch available at time of analysis. A proof-of-concept is publicly available via the GitHub Security Advisory, and three distinct exploitation channels have been demonstrated: direct credential exfiltration from cloud metadata services, internal port scanning via differential error responses, and triggering of internal APIs (Elasticsearch, etcd, Consul, CI/CD webhooks).
Authorization bypass in phpMyFAQ versions before 4.1.2 allows authenticated frontend users to access admin-only API endpoints and retrieve sensitive backend configuration data. The vulnerability stems from admin-api routes checking only login status (isLoggedIn) without verifying administrative privileges, enabling any valid user account to query dashboard versions, LDAP configuration details, Elasticsearch statistics, and health-check data. While this is an information disclosure issue rather than direct write access, it exposes internal infrastructure details useful for reconnaissance. The low CVSS score (4.3) reflects limited confidentiality impact, but defenders should prioritize remediation in environments where backend configuration exposure aids broader attack campaigns. Vendor patch available in version 4.1.2.
Server-Side Request Forgery in @utcp/http <= 1.1.1 allows remote attackers to redirect tool invocations to internal services via malicious OpenAPI specs. An attacker hosting a malicious OpenAPI specification on a legitimate HTTPS endpoint can declare internal server URLs (e.g., http://127.0.0.1:9090 or http://169.254.169.254) in the servers array; the OpenApiConverter blindly trusts these URLs without revalidation during tool invocation, enabling access to cloud metadata endpoints, internal databases, and loopback services. Additionally, a prefix-bypass in hostname validation (startsWith check) allows URLs like http://localhost.evil.com to bypass discovery-time restrictions. Patch version 1.1.2 is available.
Apache Airflow Elasticsearch provider writes embedded credentials from the `[elasticsearch] host` configuration URL directly into task logs, allowing any user with task-log read permissions to harvest backend authentication credentials. The vulnerability affects Apache Airflow Providers Elasticsearch versions before 6.5.3 and has been patched by stripping userinfo from the host URL before logging. EPSS exploitation probability is low (0.02%, percentile 4%), indicating limited real-world exploitation despite the sensitive nature of credential exposure.
Server-Side Request Forgery in utcp-http allows remote attackers to access internal cloud metadata endpoints and firewalled services by hosting a malicious OpenAPI specification on a legitimate HTTPS endpoint that declares internal server URLs, which are then blindly trusted during tool invocation without revalidation. The vulnerability affects utcp-http versions 1.1.1 and earlier, where `call_tool()` and `call_tool_streaming()` reuse previously resolved URLs from OpenAPI specs without re-checking security constraints, combined with a string-prefix bypass (`localhost.evil.com` bypassing `startswith` checks). This is a blind SSRF that exposes cloud metadata (AWS/GCP credentials from 169.254.169.254), internal services like Elasticsearch and Redis, and enables exfiltration via LLM responses when combined with prompt injection. No public exploit code or active exploitation is currently identified, but the vulnerability requires only network-level access and user interaction (convincing an LLM agent to register a malicious tool).
Cryptographic signature verification bypass in Elastic Package Registry versions 0.1.0 through 1.37.0 allows an adversary-in-the-middle, or an attacker with influence over a self-hosted registry's served content, to substitute tampered packages that are accepted without triggering integrity check failures. The flaw (CWE-347) undermines supply-chain integrity for organizations running self-hosted registry instances. No active exploitation is confirmed (SSVC: exploitation none; EPSS 0.02%), but the high integrity impact and zero-privilege-required vector make patching to 1.38.0 a priority for self-hosted deployments.
Spring Boot's Elasticsearch auto-configuration omits hostname verification when an SSL bundle is used, opening TLS connections to the Elasticsearch server to man-in-the-middle interception by an attacker on the adjacent network. Affected versions are 4.0.0 through 4.0.5; only deployments explicitly configured with an SSL bundle are exposed. No active exploitation is confirmed (absent from CISA KEV, EPSS 0.01% at the 3rd percentile), and VMware has released a fix in version 4.0.6.
Stored cross-site scripting (XSS) in Mahara before 25.04.2 and 24.04.11 allows unauthenticated remote attackers to inject malicious JavaScript via unsanitized search query parameters in the 'search site' feature when the Elasticsearch7 search plugin is enabled. The vulnerability has a CVSS score of 6.1 (moderate) with network attack vector and user interaction required (clicking a crafted search link), resulting in partial confidentiality and integrity impact. No active exploitation has been confirmed by CISA KEV, and no public exploit code is documented at the time of analysis.
Denial of service in Kibana's automatic import feature allows authenticated users to trigger uncontrolled resource consumption by submitting specially crafted requests with excessively large input values. When multiple such requests are sent concurrently, backend services become unstable, resulting in service disruption across all users. CVSS 6.5 (medium severity) reflects the authenticated attack requirement and high availability impact without confidentiality or integrity compromise.
Kibana's Fleet agent management endpoint fails to enforce space-scoped access controls, allowing authenticated users with Fleet privileges in one space to retrieve sensitive Fleet Server policy details from unauthorized spaces including policy names, operational identifiers, and infrastructure linkage information. The vulnerability affects Kibana across multiple versions and requires valid user authentication with Fleet agent management permissions, resulting in cross-space information disclosure without the ability to modify data.
Authorization bypass in Elastic Kibana allows authenticated users with limited Fleet privileges to retrieve sensitive configuration data including private keys and authentication tokens through an internal API endpoint. The vulnerability affects network-accessible instances and bypasses intended privilege boundaries by returning full configuration objects without proper authorization checks. CVSS score of 7.7 reflects high confidentiality impact with scope change. No public exploit identified at time of analysis, though the attack vector is straightforward for authenticated users.
Local privilege escalation in Dell Elastic Cloud Storage (≤3.8.1.7) and ObjectScale (<4.1.0.3, =4.2.0.0) allows authenticated users with low privileges to extract credentials from log files and escalate to compromised account privileges. CVSS 7.8 (High). No public exploit identified at time of analysis. EPSS data not available, but local access requirement and low attack complexity suggest moderate exploitation likelihood in multi-tenant or shared administrative environments.
Server-side request forgery (SSRF) in Dataease SQLBot up to version 1.6.0 allows high-privileged remote attackers to manipulate the 'address' argument in the Elasticsearch Handler component (get_es_data_by_http function), enabling unauthorized HTTP requests to internal or external systems. The vulnerability has publicly available exploit code and vendor-released patch version 1.7.0 addresses the issue.
Search Guard FLX versions 1.0.0 through 4.0.1 leak user credentials into audit logs when users authenticate through Kibana, exposing plaintext authentication material to any system administrator or user with log access. The vulnerability requires high-privilege access to exploit and affects only confidentiality, but the presence of credentials in audit logs creates a persistent information disclosure risk that persists across backup and archival systems.
Metricbeat's Prometheus remote_write HTTP handler is vulnerable to denial of service through excessive memory allocation when processing specially crafted requests from authenticated network-adjacent attackers. An attacker with local privileges can trigger unbounded memory allocation to exhaust system resources and crash the service. No patch is currently available for this vulnerability.
A Denial of Service vulnerability exists in Kibana's Timelion visualization plugin that allows authenticated users to trigger excessive memory allocation through improper validation of specially crafted Timelion expressions. An attacker with valid Kibana credentials can overwrite internal series data properties with excessively large quantity values, causing the application to exhaust system resources and become unavailable. This is a network-accessible vulnerability requiring low privileges with a CVSS score of 6.5 and documented as a confirmed denial-of-service attack vector affecting multiple active Kibana versions.
Kibana's Detection Rule Management lacks proper authorization controls, allowing authenticated users with rule management privileges to configure unauthorized endpoint response actions including host isolation and process termination. An attacker with these privileges could exploit this missing access control to execute sensitive endpoint operations beyond their intended scope. No patch is currently available for this medium-severity vulnerability affecting Elastic products.
Packetbeat contains an improper array index validation vulnerability (CWE-129) in its protocol parser components that allows attackers to trigger out-of-bounds read operations through specially crafted network packets. Affected versions include Packetbeat 8.0.0 through 8.19.10 and 9.0.0 through 9.2.4, with the vulnerability requiring network-level access or traffic control to the monitored interface. An attacker exploiting this flaw can cause denial of service through application crashes or resource exhaustion; while the CVSS score of 5.7 indicates moderate severity and there is no indication of widespread active exploitation in public KEV databases, the patch availability through Elastic's security update (ESA-2026-11) released in version 8.19.11 and 9.2.5 suggests this is a confirmed and prioritized vulnerability worthy of timely remediation.
An unauthenticated Server-Side Request Forgery (SSRF) and Local File Read vulnerability exists in the Admidio SSO metadata fetch endpoint, which accepts arbitrary URLs via GET parameter and passes them directly to file_get_contents() after validating only with PHP's FILTER_VALIDATE_URL-a format checker that does not block dangerous URI schemes. An authenticated administrator can exploit this to read arbitrary local files (including database credentials from config.php), probe internal network services, or fetch cloud instance metadata (such as AWS IAM credentials from 169.254.169.254). A proof-of-concept demonstrating all attack vectors has been published; CVSS 6.8 reflects high confidentiality impact but is mitigated by the requirement for administrator privileges.
CRLF injection in undici's HTTP upgrade handling allows authenticated attackers to inject arbitrary headers and perform request smuggling attacks against backend services like Redis and Elasticsearch when user input is passed unsanitized to the upgrade option. The vulnerability stems from insufficient validation of the upgrade parameter before writing to the socket, enabling attackers to terminate HTTP requests prematurely and route malicious data to non-HTTP protocols. This requires prior authentication and user interaction, with no patch currently available.
Kibana's Timelion component is vulnerable to denial of service through uncontrolled resource consumption when processing malicious input data, affecting authenticated users with network access to the application.

An unauthenticated attacker on the network can exploit this to crash monitoring services without user interaction. No patch is currently available.
A low-privileged authenticated user can cause a persistent denial of service in Elasticsearch by submitting oversized user settings data, leading to an out-of-memory crash. The flaw is rated CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) and affects versions prior to 8.19.9, 9.1.9, and 9.2.3. No public exploit code has been identified, and EPSS is low at 0.32% (23rd percentile).
Authentication bypass in the Elasticsearch PKI realm lets a remote, unauthenticated attacker who presents a specially crafted X.509 client certificate - signed by a Certificate Authority the cluster already trusts - be resolved to another user's identity, granting that user's read and write privileges (CVSS 3.1:7.4, C:H/I:H/A:N). Exploitation is gated by two prerequisites: the PKI realm must be explicitly enabled and configured for client-certificate authentication (it is not a default mode), and the attacker must hold a certificate issued by a CA in the cluster's trusted set, so realistic exposure is limited to deployments whose trusted CA issues certificates beyond a small high-trust population. No public exploit code has been identified at time of analysis, and the issue is not listed in CISA KEV; Elastic has published a fix in the ESA-2025-27 advisory covering Elasticsearch 8.19.8, 9.1.8, and 9.2.2.

The vulnerability affects ECE versions prior to 3.8.2 and 4.0.2, and requires the attacker to already possess admin privileges; no public exploit code has been identified at time of analysis. Elastic has assigned a CVSS score of 7.2 (High) with vector AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H.
Information disclosure in Elasticsearch audit logs allows an authenticated low-privilege attacker with adjacent network access and read access to the audit log to obtain sensitive data when audit logging is enabled and configured to log reindex API requests. The issue is non-default (auditing must be explicitly turned on), requires high attack complexity per our assessment, and affects confidentiality only with no integrity or availability impact. No public exploit identified at time of analysis, and EPSS is low at 0.25% (15th percentile); the NVD base score is 5.7 but our assessment suggests a modest-priority issue rather than a high-severity emergency.
Stored cross-site scripting in Elastic Kibana lets an authenticated user who can create or modify persistent content, such as saved objects, dashboards, or similar rendered fields, inject a payload that later executes in the browser of any other user viewing that content. Exploitation requires a valid low-privileged Kibana account plus a second victim (often a higher-privileged operator) actively opening the affected page, and impact is limited to low confidentiality and integrity within the victim's browser session. There is no confirmed active exploitation (not in CISA KEV) and no public exploit identified at time of analysis; EPSS is low at 0.23% (13th percentile), so this is a routine-patching-priority moderate-severity issue rather than an emergency.

No public exploit code or active exploitation is known, and with a low EPSS score (0.27%), this is assessed as a moderate, not a priority, issue.
Authenticated users holding only read-only API access in Nagios Log Server versions prior to 2024R1.3.2 can stop the underlying Elasticsearch service by calling the system stop endpoint with the elasticsearch subsystem parameter, degrading availability of the log ingestion, indexing, and search stack. The vulnerability is an incorrect authorization flaw (CWE-863) rated CVSS 6.5 with a PR:L vector, meaning the attacker must already possess valid credentials - no unauthenticated path exists - and impact is limited to availability with no data disclosure or modification. Publicly available exploit code exists (a GitHub proof-of-concept), and EPSS places the issue at roughly 2.77% (86th percentile), but there is no confirmation of active exploitation in CISA KEV; a vendor fix is available in 2024R1.3.2.
Stored cross-site scripting in Elastic Kibana's Cases file-upload feature lets an authenticated user with case attachment privileges plant a crafted file whose payload executes as script in a different user's browser when that case is opened. Elastic scores it CVSS 5.4 (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N), meaning exploitation needs a valid low-privileged account plus victim interaction, and the impact is limited to the viewing user's browser session and Kibana privilege level. No public exploit identified at time of analysis, it is not in CISA KEV, EPSS is 0.24% (14th percentile), and vendor-released fixes exist in 8.18.8, 8.19.5, 9.0.8, and 9.1.5.
