Security Vulnerabilities
OpenClaw versions prior to 2026.2.22 inject the x-OpenClaw-relay-token header into Chrome CDP probe traffic on loopback interfaces, allowing local processes to capture the Gateway authentication token. An attacker controlling a loopback port can intercept CDP reachability probes to the /json/version endpoint and reuse the leaked token as Gateway bearer authentication.

OpenClaw versions prior to 2026.2.23 contain an exec approval bypass vulnerability in allowlist mode where allow-always grants could be circumvented through unrecognized multiplexer shell wrappers like busybox and toybox sh -c commands. Attackers can exploit this by invoking arbitrary payloads under the same multiplexer wrapper to satisfy stored allowlist rules, bypassing intended execution restrictions.

OpenClaw versions prior to 2026.2.21 fail to filter dangerous process-control environment variables from config env.vars, allowing startup-time code execution. Attackers can inject variables like NODE_OPTIONS or LD_* through configuration to execute arbitrary code in the OpenClaw gateway service runtime context.

OpenClaw versions prior to 2026.2.21 contain an approval-integrity mismatch vulnerability in system.run that allows authenticated operators to execute arbitrary trailing arguments after cmd.exe /c while approval text reflects only a benign command. Attackers can smuggle malicious arguments through cmd.exe /c to achieve local command execution on trusted Windows nodes with mismatched audit logs.

OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in the safeBins configuration that allows attackers to invoke external helpers through the compress-program option. When sort is explicitly added to tools.exec.safeBins, remote attackers can bypass intended safe-bin approval constraints by leveraging the compress-program parameter to execute unauthorized external programs.

xiaoheiFS is a self-hosted financial and operational system for cloud service businesses. In versions up to and including 0.3.15, the standard plugin system allows admins to upload a ZIP file containing a binary and a `manifest.json`. The server trusts the `binaries` field in the manifest and executes the specified file without any validation of its contents or behavior, leading to Remote Code Execution (RCE). Version 0.4.0 fixes the issue.

xiaoheiFS is a self-hosted financial and operational system for cloud service businesses. In versions up to and including 0.3.15, the `AdminPaymentPluginUpload` endpoint lets admins upload any file to `plugins/payment/`. It only checks a hardcoded password (`qweasd123456`) and ignores file content. A background watcher (`StartWatcher`) then scans this folder every 5 seconds. If it finds a new executable, it runs it immediately, resulting in RCE. Version 4.0.0 fixes the issue.

Next.js is a React framework for building full-stack web applications. Starting in version 9.5.0 and prior to versions 15.5.13 and 16.1.7, when Next.js rewrites proxy traffic to an external backend, a crafted `DELETE`/`OPTIONS` request using `Transfer-Encoding: chunked` could trigger request boundary disagreement between the proxy and backend. This could allow request smuggling through rewritten routes. An attacker could smuggle a second request to unintended backend routes (for example, internal/admin endpoints), bypassing assumptions that only the configured rewrite destination/path is reachable. This does not impact applications hosted on providers that handle rewrites at the CDN level, such as Vercel. The vulnerability originated in an upstream library vendored by Next.js. It is fixed in Next.js 15.5.13 and 16.1.7 by updating that dependency’s behavior so `content-length: 0` is added only when both `content-length` and `transfer-encoding` are absent, and `transfer-encoding` is no longer removed in that code path. If upgrading is not immediately possible, block chunked `DELETE`/`OPTIONS` requests on rewritten routes at the edge/proxy, and/or enforce authentication/authorization on backend routes.

Next.js is a React framework for building full-stack web applications. Starting in version 16.0.1 and prior to version 16.1.7, a request containing the `next-resume: 1` header (corresponding with a PPR resume request) would buffer request bodies without consistently enforcing `maxPostponedStateSize` in certain setups. The previous mitigation protected minimal-mode deployments, but equivalent non-minimal deployments remained vulnerable to the same unbounded postponed resume-body buffering behavior. In applications using the App Router with Partial Prerendering capability enabled (via `experimental.ppr` or `cacheComponents`), an attacker could send oversized `next-resume` POST payloads that were buffered without consistent size enforcement in non-minimal deployments, causing excessive memory usage and potential denial of service. This is fixed in version 16.1.7 by enforcing size limits across all postponed-body buffering paths and erroring when limits are exceeded. If upgrading is not immediately possible, block requests containing the `next-resume` header, as this is never valid to be sent from an untrusted client.

Next.js is a React framework for building full-stack web applications. Starting in version 10.0.0 and prior to version 16.1.7, the default Next.js image optimization disk cache (`/_next/image`) did not have a configurable upper bound, allowing unbounded cache growth. An attacker could generate many unique image-optimization variants and exhaust disk space, causing denial of service. This is fixed in version 16.1.7 by adding an LRU-backed disk cache with `images.maximumDiskCacheSize`, including eviction of least-recently-used entries when the limit is exceeded. Setting `maximumDiskCacheSize: 0` disables disk caching. If upgrading is not immediately possible, periodically clean `.next/cache/images` and/or reduce variant cardinality (e.g., tighten values for `images.localPatterns`, `images.remotePatterns`, and `images.qualities`).
