TG8 Firewall Unauthenticated User Password Disclosure

TG8 Firewall exposes a directory such as /data/ over HTTP without authentication. This directory stores credential files for previously logged-in users. A remote unauthenticated attacker can enumerate and download files within the directory to obtain valid account usernames and passwords, leading to loss of confidentiality and further unauthorized access.

Tandoor Recipes module allows SQLite database to be externally accessible with the default settings

Tandoor Recipes is a recipe manager than can be installed with the Nix package manager. Starting in version 23.05 and prior to version 26.05, when using the default configuration of Tandoor Recipes, specifically using SQLite and default `MEDIA_ROOT`, the full database file may be externally accessible, potentially on the Internet. The root cause is that the NixOS module configures the working directory of Tandoor Recipes, as well as the value of `MEDIA_ROOT`, to be `/var/lib/tandoor-recipes`. This causes Tandoor Recipes to create its `db.sqlite3` database file in the same directory as `MEDIA_ROOT` causing it to be accessible without authentication through HTTP like any other media file. This is the case when using `GUNICORN_MEDIA=1` or when using a web server like nginx to serve media files. NixOS 26.05 changes the default value of `MEDIA_ROOT` to a sub folder of the data directory. This only applies to configurations with `system.stateVersion` >= 26.05. For older configurations, one of the workarounds should be applied instead. NixOS 25.11 has received a backport of this patch, though it doesn't fix this vulnerability without user intervention. A recommended workaround is to move `MEDIA_ROOT` into a subdirectory. Non-recommended workarounds include switching to PostgreSQL or disallowing access to `db.sqlite3`.

angular-server-side-configuration information disclosure vulnerability in monorepo with node.js backend

angular-server-side-configuration helps configure an angular application at runtime on the server or in a docker container via environment variables. angular-server-side-configuration detects used environment variables in TypeScript (.ts) files during build time of an Angular CLI project. The detected environment variables are written to a ngssc.json file in the output directory. During deployment of an Angular based app, the environment variables based on the variables from ngssc.json are inserted into the apps index.html (or defined index file). With version 15.0.0 the environment variable detection was widened to the entire project, relative to the angular.json file from the Angular CLI. In a monorepo setup, this could lead to environment variables intended for a backend/service to be detected and written to the ngssc.json, which would then be populated and exposed via index.html. This has NO IMPACT, in a plain Angular project that has no backend component. This vulnerability has been mitigated in version 15.1.0, by adding an option `searchPattern` which restricts the detection file range by default. As a workaround, manually edit or create ngssc.json or run script after ngssc.json generation.

Ubee EVW3226 Unauthenticated Backup File Disclosure

Ubee EVW3226 cable modem/routers firmware versions up to and including 1.0.20 store configuration backup files in the web root after they are generated for download. These backup files remain accessible without authentication until the next reboot. A remote attacker on the local network can request 'Configuration_file.cfg' directly to obtain the backup archive. Because backup files are not encrypted, they expose sensitive information including the plaintext admin password, allowing full compromise of the device.
