The Reachy Mini daemon exposes an HTTP API for managing the robot. Its app installation endpoint, POST /apps/install in src/reachy_mini/daemon/app/routers/apps.py, has no authentication. The handler's only dependency is Depends(get_app_manager), which just hands back the manager object from application state, so nothing in the chain ever checks a credential. The endpoint takes an AppInfo body naming a Hugging Face Space. The daemon downloads that Space and installs it as a Python package through install_package in src/reachy_mini/apps/sources/local_common_venv.py, using uv or pip. Installing a Python package runs the package's own build and setup code, so whoever chooses the Space chooses what code the robot runs. Anyone can publish a public Hugging Face Space, so this is not a meaningful restriction on the attacker. How far this reaches depends on the model. In _resolve_bind_host in src/reachy_mini/daemon/app/main.py the daemon binds 0.0.0.0 when it runs as the wireless version and 127.0.0.1 otherwise, with the vendor's own comment explaining that the robot has to be reachable on the LAN. On a wireless unit, then, any host on the same network can install and run code on the robot without credentials. One related change has already shipped but does not fix this. Version 1.8.2 replaced the wildcard CORS policy with an allow list of localhost and Tauri origins. That closes the browser drive-by route, where a web page the victim visits silently calls the endpoint in the background. It has no effect on this issue: CORS is enforced by browsers and governs whether script may read a response, while a direct HTTP request from another machine on the network involves no browser, no preflight and no CORS check at all.

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. Prior to 3.7.2, Joplin Desktop for Windows omits publisherName from packages/app-desktop/package.json, so the generated app-update.yml causes NsisUpdater.verifySignature() to skip comparison of a downloaded update's Authenticode signer with Joplin's signer. An attacker who controls the update delivery path can replace the update metadata and installer, and the client accepts an installer signed by another publisher or left unsigned after the user approves installation. Successful exploitation runs attacker-controlled code with the user's privileges and can compromise notes, credentials, and local data. This issue is fixed in version 3.7.2.

A vulnerability was identified in spatie Scotty up to 1.4.2. Affected is the function SelfUpdater::update of the file app/Updater/SelfUpdater.php of the component Self Update Handler. Such manipulation leads to download of code without integrity check. It is possible to launch the attack remotely. Upgrading to version 1.4.3 is able to address this issue. The name of the patch is 4b4e11bfc98e3a2159bb2b3d9b040293fcc44744. It is advisable to upgrade the affected component.

Dell SmartFabric OS10 Software versions prior to 10.6.1.3 have a vulnerability where code is downloaded without an integrity check. This flaw could allow a high privileged remote attacker to execute arbitrary code. The vulnerability is identified as CWE-494 and has a critical severity rating with a CVSS score of 9.1.

Dell ThinOS 10 versions prior to 2605_10.2616 have a vulnerability where code can be downloaded without an integrity check. This flaw allows an unauthenticated attacker with physical access to potentially execute arbitrary code on the device.

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains a Download of Code Without Integrity Check vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to command execution.

A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). A special maintenance mode can be activated via a physical key sequence during device boot, in which the device downloads and executes program code from a network server without verifying its authenticity or integrity. This could allow an attacker with physical access to the device to upload and execute arbitrary, unsigned code.

A vulnerability in Hugging Face Transformers (versions 4.57.0 to 5.16.1) allows remote Python files to be written to local disk without user consent when using GenerativePreTrainedModel.load_custom_generate(). The function fetches and caches a remote module file before performing the required trust_remote_code consent check, inverting the security model enforced by other code-loading paths (such as AutoConfig, AutoModel, and AutoTokenizer). As a result, attacker‑controlled Python code from custom_generate/generate.py is copied into the user’s ~/.cache/huggingface/modules directory even if the user declines the trust prompt. Although execution is correctly gated, the file write is not reversible and can persist across sessions. This can lead to persistent, unauthorized files on disk and stale cache collisions where cached attacker code may later be executed during trusted model loads. The issue stems from an unconditional file write in dynamic_module_utils.py prior to any trust verification.

The GraphiQL page bundled with Spring for GraphQL loads JavaScript libraries from a public CDN, without Subresource Integrity checks. An attacker can inject malicious code in those scripts and execute arbitrary code on the browser loading the GraphiQL page. Spring for GraphQL 2.0.0 - 2.0.4 Spring for GraphQL 1.4.0 - 1.4.6 Spring for GraphQL 1.1.0 - 1.3.9 Spring for GraphQL 1.0.0 - 1.0.7

CVE-2026-21810 affects HCL BigFix Quantum Risk Analyzer version 2.0.1.47 and involves a hardcoded external resource reference combined with a lack of binary integrity checks. This vulnerability could allow an attacker with high privileges to modify the binary, potentially leading to unauthorized code changes. The CVSS score is 4.4, indicating a medium severity level. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
