    "summary": "## Vulnerability Details **File**: `icongenie/lib/utils/get-assets-files.js` (line 35, `absoluteName: join(appDir, asset.folder, asset.name)`) **Validation gap**: `icongenie/lib/utils/validate-profile-object.js` (`assetsSchema`) — `folder`/`name` only checked with `Joi.string().required().min(1)`, no restriction on `..` sequences or absolute paths **Entry point**: `icongenie/lib/runner/generate.js` (`generate(argv)`) — `profile.assets = userProfile.assets`, loaded verbatim from a user-supplied JSON file via `--profile ` ### Root Cause `icongenie generate --profile ` loads a JSON \"profile\" describing icon/splashscreen assets to generate, where each asset entry has a `folder`/`name` describing where the generated file should be written relative to the Quasar project directory (`appDir`). `getAssetsFiles()` builds the write target with `join(appDir, asset.folder, asset.name)`. Node's `path.join` normalizes `..` segments arithmetically and does not clamp the result to stay inside `appDir`. The only validation before this (`validateProfileObject` → Joi `assetsSchema`) checks that `folder`/`name` are non-empty strings, with no `..` rejection and no containment check against `appDir`. A profile setting `folder: \"../../../../../../tmp/pwned-by-icongenie\"` sails through validation unmodified, and the generator writes attacker-influenced icon/splashscreen content to that path via a direct `writeFile`/`sharp().toFile()` call. ### Attack Scenario 1. Attacker publishes a \"ready-made Icon ",
