### Summary Any unauthenticated attacker can bypass the localhost restrictions posed by the application and utilize this to create arbitrary packages. ### Details Any unauthenticated attacker can bypass the localhost restrictions posed by the application and utilize this to create arbitrary packages. This is done by changing the `Host` header to the value of `127.0.0.1:9666`. ### PoC The application has middleware that prevents access to several routes by checking whether the `Host` header has a specific value. We bypassed this restriction. https://github.com/pyload/pyload/blob/4159a1191ec4fe6d927e57a9c4bb8f54e16c381d/src/pyload/webui/app/blueprints/cnl_blueprint.py#L21-L36 ```python #: decorator def local_check(func): @wraps(func) def wrapper(*args, **kwargs): remote_addr = flask.request.environ.get("REMOTE_ADDR", "0") http_host = flask.request.environ.get("HTTP_HOST", "0") if remote_addr in ("127.0.0.1", "::ffff:127.0.0.1", "::1", "localhost") or h...

### Summary A command injection vulnerability exists in the `mcp-server-kubernetes` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.execSync`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.). ### Details The MCP Server exposes tools (`kubectl_scale`, `kubectl_patch` , `explain_resource`, etc) to perform several kubernetes operations. An MCP Client can be instructed to execute additional actions for example via prompt injection when asked to read pod logs. Below some example of vulnerable code and different ways to test this vulnerability including a real example of indirect prompt injection that can lead to ...

### Summary Sending a message that modifies the validator set at the epoch boundary halts the chain. ### Impact Denial of Service - Comos-sdk prevents modifying the validator set from two different modules - https://github.com/cosmos/cosmos-sdk/blob/release/v0.50.x/types/module/module.go#L811. Such an operation leads to panic and chain halt. ### Detailed Post mortem https://boiling-lake-106.notion.site/2025-06-18-Genesis-mainnet-chain-halt-post-mortem-229f60cc1b5f80b7adf5e3ea0541ea87

### Summary Note: [originally posted on H1](https://hackerone.com/reports/3117837) but closed. Cross-posting over to here in abundance of caution instead of a public issue. When utilising the Cloudflare Vite plugin in its default configuration, all files are exposed by the local dev server, including files in the root directory that contain secret information such as: - `.env` - `.dev.vars` ### PoC 1. Create a Workers project that utilises the `@cloudflare/vite-plugin`. For example: - `npm create cloudflare@latest` - select Framework Starter -> React 2. Add any secret files to test if they're accessible. `echo foobar=secret > .dev.vars` for example 3. Run `npm run dev` to start the dev server (after running `npm ci` if necessary to install dependencies) and then hit the following to expose information: `curl http://localhost:5173/.env` may expose any secrets in this file `curl http://localhost:5173/.dev.vars` may expose any secrets in this file `curl http://localhost:5173/packa...

In yet another instance of threat actors repurposing legitimate tools for malicious purposes, it has been discovered that hackers are exploiting a popular red teaming tool called Shellter to distribute stealer malware. The company behind the software said a company that had recently purchased Shellter Elite licenses leaked their copy, prompting malicious actors to weaponize the tool for

### Summary A command injection vulnerability exists in the `node-code-sandbox-mcp` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.execSync`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges on the host machine, bypassing the sandbox protection of running code inside docker. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.). ### Details The MCP Server exposes tools to run code inside a docker container. An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to generate code that read a file. Below some example of vulnerable code and different ways to test this vulnerability including a real example o...

Cybersecurity researchers have flagged a supply chain attack targeting a Microsoft Visual Studio Code (VS Code) extension called Ethcode that has been installed a little over 6,000 times. The compromise, per ReversingLabs, occurred via a GitHub pull request that was opened by a user named Airez299 on June 17, 2025. First released by 7finney in 2022, Ethcode is a VS Code extension that's used to

Cybersecurity researchers are calling attention to a malware campaign that's targeting security flaws in TBK digital video recorders (DVRs) and Four-Faith routers to rope the devices into a new botnet called RondoDox. The vulnerabilities in question include CVE-2024-3721, a medium-severity command injection vulnerability affecting TBK DVR-4104 and DVR-4216 DVRs, and CVE-2024-12856, an operating
