Sep 22, 2026Netdata is an open source observability tool.CVE-2026-83597 · Other software · netdata · reported by GitHubHigh 7
Netdata is an open source observability tool. From version 2.0.0 until 2.10.4, Netdata Windows Agent MSI repair launches powershell.exe and wevtutil.exe as elevated interactive processes in the initiating user's desktop session. A low-privileged local user who triggers repair can interact with or hijack those visible process windows to execute arbitrary commands with SYSTEM privileges. This issue is fixed in stable version 2.10.4.

Sep 22, 2026Netdata is an open source observability tool.CVE-2026-83603 · Other software · netdata · reported by GitHubHigh 8.4
Netdata is an open source observability tool. Prior to 2.10.4, the setuid-root ndsudo helper command fail2ban-client-status-socket in src/collectors/utils/ndsudo.c accepts a caller-controlled --socket_path from the low-privileged netdata service account. The account can direct root fail2ban-client to a malicious UNIX socket, and fail2ban/client/csocket.py CSocket.receive() passes the returned data to pickle.loads(), allowing attacker-controlled code to execute as root on systems with fail2ban-client installed. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.

Netdata is an open source observability tool. From 2.0.0 until 2.11.0, Netdata registers /api/v3/settings in src/web/api/v3/web_api_v3.c with HTTP_ACL_NOCHECK and HTTP_ACCESS_ANONYMOUS_DATA, causing unauthenticated PUT requests handled by src/web/api/v3/api_v3_settings.c to bypass operator-configured allow dashboard from IP restrictions. A network-reachable caller can persist attacker-controlled JSON in {varlib}/settings/default.json, manipulate its version counter, and use repeated near-20 MiB writes to consume disk space, although the file does not control collection or security policy. This vulnerability is fixed in 2.11.0.

Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized DIMENSION SLOT value that str2ull_encoded passes to pluginsd_rrddim_put_to_slot in src/plugins.d/pluginsd_internals.h without an upper bound. prd_array_create in src/database/rrdset-pluginsd-array.h can then wrap the size_t allocation calculation while retaining the original large array size, causing the subsequent initialization loop to write beyond the undersized heap allocation and crash the parent agent. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.

Netdata is an open source observability tool. Prior to 2.10.4, an authenticated child agent can send an oversized CHART SLOT value that str2ull_encoded passes to pluginsd_rrdset_cache_put_to_slot in src/plugins.d/pluginsd_internals.h. The accepted slot drives reallocz to request an approximately 16 GiB chart-pointer array, and allocation failure invokes fatal and aborts the parent Netdata agent, repeatedly disabling centralized monitoring while stream access persists. This issue is fixed in version 2.10.4 and nightly build 2.10.0-782-nightly.

Netdata is an open source observability tool. Prior to 2.11.0, Netdata's unauthenticated WebSocket server negotiates permessage-deflate before authentication, and src/web/websocket/websocket-compression.c allows websocket_client_decompress_message() to grow decompressed output toward WS_MAX_DECOMPRESSED_SIZE without enforcing a compressed-to-decompressed ratio. Small highly compressed frames can therefore cause large server-side allocations, and repeated concurrent connections can exhaust memory and terminate monitoring. This vulnerability is fixed in 2.11.0.

Netdata is an open source observability tool. From rom 2.0.0 until 2.10.4, during Netdata Windows Agent MSI repair, powershell.exe runs as SYSTEM without -NoProfile and loads %USERPROFILE%\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1 from the low-privileged user who initiated repair. Commands placed in that profile before repair therefore execute with SYSTEM privileges. This vulnerability is fixed in 2.10.4.

Jul 2, 2026Netdata before 2.3.1 reflects the user-supplied love query parameter of the api/v2/ilove.svg and api/v3/ilove.svg endpoints verbatim into the generated SVG docuCVE-2025-71385 · Other software · netdata · reported by VulnCheckMedium 5.1
Netdata before 2.3.1 reflects the user-supplied love query parameter of the api/v2/ilove.svg and api/v3/ilove.svg endpoints verbatim into the generated SVG document (into a text element) without HTML or XML escaping, and serves the response with Content-Type image/svg+xml. An attacker can craft a URL such as /api/v2/ilove.svg?love=<script>...</script>; when a victim navigates to it the injected script executes in the victim browser in the origin of the Netdata instance (reflected cross-site scripting). These endpoints are registered with HTTP_ACL_NOCHECK and anonymous access and, because bearer-token protection is disabled by default, are reachable without authentication on a default Netdata agent. The issue was resolved by removing the ilove endpoint.

Apr 12, 2024Netdata is an open source observability tool.CVE-2024-32019 · Other software · netdata · reported by GitHubHigh 8.8
Netdata is an open source observability tool. In affected versions the `ndsudo` tool shipped with affected versions of the Netdata Agent allows an attacker to run arbitrary programs with root permissions. The `ndsudo` tool is packaged as a `root`-owned executable with the SUID bit set. It only runs a restricted set of external commands, but its search paths are supplied by the `PATH` environment variable. This allows an attacker to control where `ndsudo` looks for these commands, which may be a path the attacker has write access to. This may lead to local privilege escalation. This vulnerability has been addressed in versions 1.45.3 and 1.45.2-169. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Jan 13, 2023Netdata is an open source option for real-time infrastructure monitoring and troubleshooting.CVE-2023-22497 · Other software · netdata · reported by GitHubMedium 6.5
Netdata is an open source option for real-time infrastructure monitoring and troubleshooting. Each Netdata Agent has an automatically generated MACHINE GUID. It is generated when the agent first starts and it is saved to disk, so that it will persist across restarts and reboots. Anyone who has access to a Netdata Agent has access to its MACHINE_GUID. Streaming is a feature that allows a Netdata Agent to act as parent for other Netdata Agents (children), offloading children from various functions (increased data retention, ML, health monitoring, etc) that can now be handled by the parent Agent. Configuration is done via `stream.conf`. On the parent side, users configure in `stream.conf` an API key (any random UUID can do) to provide common configuration for all children using this API key and per MACHINE GUID configuration to customize the configuration for each child. The way this was implemented, allowed an attacker to use a valid MACHINE_GUID as an API key. This affects all users who expose their Netdata Agents (children) to non-trusted users and they also expose to the same users Netdata Agent parents that aggregate data from all these children. The problem has been fixed in: Ne

Jan 13, 2023Netdata is an open source option for real-time infrastructure monitoring and troubleshooting.CVE-2023-22496 · Other software · netdata · reported by GitHubHigh 8.1
Netdata is an open source option for real-time infrastructure monitoring and troubleshooting. An attacker with the ability to establish a streaming connection can execute arbitrary commands on the targeted Netdata agent. When an alert is triggered, the function `health_alarm_execute` is called. This function performs different checks and then enqueues a command by calling `spawn_enq_cmd`. This command is populated with several arguments that are not sanitized. One of them is the `registry_hostname` of the node for which the alert is raised. By providing a specially crafted `registry_hostname` as part of the health data that is streamed to a Netdata (parent) agent, an attacker can execute arbitrary commands at the remote host as a side-effect of the raised alert. Note that the commands are executed as the user running the Netdata Agent. This user is usually named `netdata`. The ability to run arbitrary commands may allow an attacker to escalate privileges by escalating other vulnerabilities in the system, as that user. The problem has been fixed in: Netdata agent v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a workaround, streaming is not enabled by default. If you have

The Netdata web application through 1.13.0 allows remote attackers to inject their own malicious HTML code into an imported snapshot, aka HTML Injection.
