+title: Fluentd is Vulnerable to Remote Code Execution (RCE) via Arbitrary
+  File Write in `${tag}` Placeholder
+date: 2026-06-26
+description: |-
+  Fluentd allows dynamically constructing file paths using the `${tag}`
+  placeholder. It was discovered that validation for this placeholder
+  was insufficient.
+
+  If a Fluentd instance is configured to receive logs from untrusted
+  sources and uses the `${tag}` placeholder in file configurations
+  (such as the `path` parameter in the `out_file` plugin), an attacker
+  can inject path traversal characters (e.g., `../`).
+
+  When combined with certain formatting options, this vulnerability allows
+  an attacker to write arbitrary files or overwrite existing files on
+  the system with attacker-controlled content, bypassing intended
+  directory restrictions.
+
+  ### Impact
+
+  This vulnerability allows for **Arbitrary File Write**, which can be
+  directly escalated to full **Remote Code Execution (RCE)**.
+  An attacker could achieve RCE by overwriting critical system files,
+  injecting executable plugins, or modifying configuration files.
+  The impact is Critical as it can lead to full system compromise without
+  any authentication, depending on the Fluentd configuration and the
+  privileges of the Fluentd process.

+title: Fluentd is Vulnerable to Exposure of Sensitive Information
+   via Monitor Agent API
+date: 2026-06-26
+description: |
+  Fluentd's Monitor Agent plugin (`in_monitor_agent`) exposes internal
+  metrics and plugin information via a REST API.
+  It was discovered that the API response (`/api/plugins.json` and
+  related endpoints) unintentionally includes internal instance
+  variables of loaded plugins.
+
+  If any plugins store sensitive information—such as database passwords,
+  API keys, or cloud credentials—in its instance variables, this
+  information may be exposed in plain text to any user or system
+  that has HTTP access to the Monitor Agent API.
+
+  ### Impact
+
+  This vulnerability allows for unauthorized information disclosure. An
+  attacker who can reach the Monitor Agent API port (default: `24220`)
+  can potentially extract sensitive credentials used by other Fluentd plugins.
+  The impact severity depends highly on the network configuration (whether
+  the Monitor Agent port is exposed to untrusted networks) and the
+  specific plugins configured in the Fluentd instance.

+title: Fluentd is Vulnerable to Denial of Service (DoS) via Gzip
+  Decompression Bomb in `in_http` and `in_forward`
+date: 2026-06-26
+description: |
+  Fluentd's `in_http` and `in_forward` plugins support receiving
+  gzip-compressed data.
+
+  While Fluentd correctly enforces size limits on the incoming
+  compressed payloads (e.g., via `body_size_limit` or `chunk_size_limit`),
+  it was discovered that there is no limit enforced on the size of the
+  decompressed data. If a Fluentd instance is exposed to untrusted
+  networks, an attacker can send a maliciously crafted, highly
+  compressed payload. When Fluentd attempts to decompress this payload
+  in memory, it will expand to an excessive size, completely bypassing
+  the intended payload size limits.
+
+  ### Impact
+
+  This vulnerability allows for a **Denial of Service (DoS)** attack
+  via memory exhaustion. The rapid memory consumption during decompression
+  can easily lead to an Out-of-Memory kill of the Fluentd process by
+  the operating  system. This results in the disruption of all log
+  collection and forwarding capabilities on the affected node.

+title: Fluentd is Vulnerable to Server-Side Request Forgery (SSRF)
+  via Placeholder Expansion in `out_http`
+date: 2026-06-26
+description: |
+  The `out_http` output plugin allows the use of placeholders (such as
+  `${tag}`) in the `endpoint` configuration parameter. It was discovered
+  that if the placeholder value is derived from untrusted user input,
+  an attacker can maliciously control the destination hostname of the
+  outbound HTTP requests made by Fluentd.
+
+  ## Impact
+
+  This vulnerability allows for a **Server-Side Request Forgery (SSRF)**
+  attack. An unauthenticated attacker can force the Fluentd node to send
+  HTTP requests to arbitrary internal services. This can lead to
+  unauthorized access to internal APIs, data exfiltration, or the
+  compromise of cloud metadata endpoints (e.g., AWS IMDS `169.254.169.254`).
