CVE-2026-59195high · fixedCVSS 8.2

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

🌐 Live API: https://api.weblens.dev 📖 Interactive docs: https://api.weblens.dev/docs 🤖 Agent guide: https://api.weblens.dev/llms.txt 🔎 Marketplace: listed on x402scan

Try it free, right now

No wallet, no signup — these are rate limited to 10 requests/hour per IP:

curl https://api.weblens.dev/r/https://example.com     # any page as markdown
curl https://api.weblens.dev/s/cloudflare+workers      # web search

Preview before you pay (free)

An agent shouldn't have to buy a call to learn what it returns. POST /preview is free and answers that up front — the live price, a one-line summary, and a real sample of the exact response shape:

curl -X POST https://api.weblens.dev/preview \
  -H "Content-Type: application/json" \
  -d '{"endpoint": "/answer"}'

{
  "endpoint": "/answer",
  "price": "$0.05",
  "currency": "USD",
  "summary": "A direct answer with inline [n] citations to real sources.",
  "sample": { "query": "...", "answer": "...", "citations": [], "confidence": 0.92 },
  "sampleType": "recorded",
  "livePreviewAvailable": false,
  "livePreviewHint": "This endpoint calls a paid upstream provider, so free live previews are not offered — the recorded sample shows the exact response shape."
}

Live vs recorded. A real, truncated live preview runs only for endpoints whose marginal cost is a plain fetch — currently /fetch/basic, /contents and /map — and only when you pass a url. Everything else is backed by a metered upstream (SerpAPI, Anthropic); running those free would burn upstream credits, so they return the recorded sample, which still shows every field name and type. An endpoint that isn't sold returns 404.

# live: the first 500 chars of the real result, for free
curl -X POST https://api.weblens.dev/preview \
  -H "Content-Type: application/json" \
  -d '{"endpoint": "/fetch/basic", "url": "https://example.com"}'

Rate limited to 10 requests/hour per IP like the rest of the free tier.

ERC-8004: receipts and feedback

ERC-8004 (Trustless Agents) keeps compact signals on-chain and the detailed documents off-chain. WebLens hosts the off-chain half — the part a service operator can run without deploying a contract. To be precise about what that is and isn't: WebLens is not registered on-chain, holds no agent id, and writes nothing to any registry.

Endpoint	What it gives you
`GET /.well-known/agent-registration.json`	The ERC-8004 registration document: name, description, image, services, `x402Support`, payment info, feedback endpoints. `registrations` is empty (no on-chain registration) and `supportedTrust` is `["feedback"]`.
`GET /receipts/{requestId}`	The receipt for a paid call — endpoint, status, outcome, price, payment method, network, pay-to. Every paid response returns `X-Receipt-Id` and `X-Receipt-Url` headers pointing here. Kept 30 days.
`POST /feedback`	Host a feedback document you author; returns `{feedbackURI, feedbackHash}` (keccak-256), the pair `giveFeedback()` expects. Required fields: `agentRegistry`, `agentId`, `clientAddress`, `createdAt`, `value`, `valueDecimals` — a missing one returns `400` naming it.
`GET /feedback/{id}`	Serves that document byte-for-byte, so its keccak-256 hash matches the `feedbackHash` you were given. This URL is the `feedbackURI`.

Two more things worth stating plainly:

A receipt's mac is a symmetric HMAC tag (the same construction as proof-of-context). Only a holder of the key can verify it — it is not a third-party-verifiable signature, and nothing here is trustless.
The buyer authors the feedback document and posts giveFeedback() themselves. WebLens only hosts the document verb
