CVE-2026-0933high · fixed

Wrangler affected by OS Command Injection in `wrangler pages deploy`

**Summary** A command injection vulnerability (CWE-78) has been found to exist in the `wrangler pages deploy` command. The issue occurs because the `--commit-hash` parameter is passed directly to a shell command without proper validation or sanitization, allowing an attacker with control of `--commit-hash` to execute arbitrary commands on the system running Wrangler. **Root cause** The `commitHash` variable, derived from user input via the `--commit-hash` CLI argument, is interpolated directl

CVE-2023-7080critical · fixedCVSS 9.3

Arbitrary remote code execution within `wrangler dev` Workers sandbox

### Impact The V8 inspector intentionally allows arbitrary code execution within the Workers sandbox for debugging. `wrangler dev` would previously start an inspector server listening on all network interfaces. This would allow an attacker on the local network to connect to the inspector and run arbitrary code. Additionally, the inspector server did not validate `Origin`/`Host` headers, granting an attacker that can trick any user on the local network into opening a malicious website the ability

Arbitrary remote file read in Wrangler dev server

### Impact Sending specially crafted HTTP requests and inspector messages to Wrangler's dev server could result in any file on the user's computer being accessible over the local network. An attacker that could trick any user on the local network into opening a malicious website could also read any file. ### Patches This issue was fixed in `wrangler@3.19.0`. Wrangler will now only serve files that are part of your bundle, or referenced by your bundle's source maps. ### Workarounds Configure Wr

Cloudflare Wrangler directory traversal vulnerability

### Impact The Wrangler command line tool (<=wrangler@3.1.0 or <=wrangler@2.20.1) was affected by a directory traversal vulnerability when running a local development server for Pages (wrangler pages dev command). This vulnerability enabled an attacker in the same network as the victim to connect to the local development server and access the victim's files present outside of the directory for the development server. ### Patches Wrangler2: Upgrade to v2.20.1 or higher.

Luogu MCP Server | 洛谷 MCP Server

中文文档

A small MCP server for searching Luogu problems, reading statements and training sets, and finding related practice. It can run locally through npm or as a hosted Streamable HTTP server.

Quick Start

Use the hosted read-only server without installing anything:

{
  "mcpServers": {
    "luogu": {
      "url": "https://luogu-mcp.ksrnyx.top/mcp"
    }
  }
}

To keep the server on your machine, use the published luogu-mcp-server package:

{
  "mcpServers": {
    "luogu": {
      "command": "npx",
      "args": ["-y", "luogu-mcp-server"]
    }
  }
}

Then ask:

Search Luogu for five beginner binary-tree problems.
Fetch Luogu P1305 with its statement and samples.
Find related practice for traversal-order confusion.

Tools

Tool	Purpose
`luogu_search_problems`	Search Luogu problems by keyword, topic, title fragment, problem id, and optional Luogu tag ids.
`luogu_fetch_problem`	Fetch one Luogu problem statement, formats, samples, tags, difficulty, and URL by `pid`.
`luogu_resolve_problem`	Resolve a Luogu URL, problem id, or title fragment, then fetch the problem.
`luogu_find_related_problems`	Mix topic/pain-point recommendations with live keyword search to find related practice.
`luogu_list_algorithm_topics`	List canonical algorithm topics, aliases, and known tag ids.
`luogu_find_topic_problems`	Find topic practice problems using aliases, tag ids, deduplication, and match reasons.
`luogu_search_problem_sets`	Search Luogu training/problem sets by keyword. Supports `type: "all"
`luogu_fetch_problem_set`	Fetch one Luogu training/problem set and problem summaries by id.
`luogu_recommend_problems`	Return seed recommendations from a topic or student pain point.
`luogu_get_user_profile`	Fetch public Luogu user profile data by uid.
`luogu_get_capabilities`	Report which LeetCode-style route features are available, auth-required, or planned.

All tools are read-only.
