What io.github.aryanduntley/pwa-debug-layer does
An AI-native debugging layer for PWAs and modern web apps. It lets an AI agent (e.g. Claude Code via MCP) see and act on your live, logged-in browser the way a developer with full DevTools open would — DOM, console, network, framework state, store state, service workers, caches, and direct interaction — as structured data the model consumes natively.

pnpm: Path traversal in configDependencies env lockfile allows symlink creation outside node_modules/.pnpm-config
## Summary `pnpm` accepts package names from the env lockfile `configDependencies` section and uses those names directly when creating config dependency symlinks under `node_modules/.pnpm-config`. A malicious repository can commit a crafted `pnpm-lock.yaml` whose env-lockfile document contains a traversal-shaped config dependency name such as `../../PWNED_CFGDEP`. During `pnpm install`, pnpm installs the config dependency and creates a symlink at a path derived from that name. In local testin

pnpm: `patch-remove` could delete project-selected files outside the patches directory
## Summary The `patch-remove` deletion-scope issue tracked as GHSA-72r4-9c5j-mj57 / CAND-PNPM-030 has been addressed in pnpm. A crafted patch entry could resolve outside the configured patches directory and cause `pnpm patch-remove` to delete an arbitrary reachable file. This patch validates the configured directory and every resolved target before unlinking anything, then deletes the final directory entry without following it. ## Security boundary - Traversal and absolute paths that resolve

pnpm: Hoisted install imports lockfile alias outside node_modules
## Summary The hoisted dependency alias issue tracked as GHSA-fr4h-3cph-29xv / CAND-PNPM-059 has been addressed in both pnpm and pacquet. A crafted lockfile alias could be joined directly under a hoisted `node_modules` directory. Traversal aliases could escape that directory, while reserved aliases such as `.bin` or `.pnpm` could overwrite pnpm-owned layout. This patch validates package-name semantics and path containment before graph insertion or filesystem work. ## Security boundary - The

pnpm: `stage download` writes outside its destination directory via manifest name/version traversal
## Summary The staged-tarball filename traversal reported as GHSA-v23m-ccfg-pq9h / CAND-PNPM-038 is fixed on `main` by [pnpm/pnpm#12303](https://github.com/pnpm/pnpm/pull/12303), merged as `65443f4bdf1f0db9c8c7dc58fee25252607e9234`. Before the fix, `pnpm stage download` derived a local filename from registry-controlled package name and version fields. A crafted manifest could escape the selected download directory and overwrite another reachable file. The merged fix validates both fields, deri
