A supply chain vulnerability in AWS CodeBuild recently put the entire AWS Console at risk. Learn how Wiz Research found the flaw and how Amazon responded to prevent a global security crisis.

### Summary A prior patch aimed to block spawning Windows batch/shell files by returning an error when a spawned path’s extension matched `.bat` or `.cmd`. That check performs a case-sensitive comparison against lowercase literals and therefore can be bypassed when the extension uses alternate casing (for example `.BAT, .Bat`, etc.). ### POC ```javascript const command = new Deno.Command('./test.BAT', { args: ['&calc.exe'], }); const child = command.spawn(); ``` This causes `calc.exe` to be launched; see the attached screenshot for evidence. **Patched in `CVE-2025-61787` — prevents execution of `.bat` and `.cmd` files:**  **Bypass of the patched vulnerability:**  ### Impact The script launches calc.exe on Windows, demonstrating that passing user-controlled argument...

### Summary The vulnerability allows an attacker to have infinite encryptions. This can lead to naive attempts at brute forcing, as well as more refined attacks with the goal to learn the server secrets. ### PoC ```js import crypto from "node:crypto"; const key = crypto.randomBytes(32); const iv = crypto.randomBytes(16); const cipher = crypto.createCipheriv("aes-256-cbc", key, iv); cipher.final() console.log(cipher); ``` ### Expected Output ```js Cipheriv { _decoder: null, _options: undefined, Symbol(kHandle): CipherBase {} } ``` ### Actual Output ```js Cipheriv { _events: { close: undefined, error: undefined, prefinish: [Function: prefinish], finish: undefined, drain: undefined, data: undefined, end: undefined, readable: undefined }, _readableState: ReadableState { highWaterMark: 65536, buffer: [], bufferIndex: 0, length: 0, pipes: [], awaitDrainWriters: null, [Symbol(kState)]: 1048844 }, _writableStat...

### Summary Invalid RPC signatures cause the server to log the shared HMAC secret (and expected signature), which exposes the secret to log readers and enables forged RPC calls. ### Details In [`crates/ecstore/src/rpc/http_auth.rs:115-122`](https://github.com/rustfs/rustfs/blob/9e162b6e9ebb874cc1d06a7b33bc4a05786578aa/crates/ecstore/src/rpc/http_auth.rs#L115-L122) , the invalid signature branch logs sensitive data: ```rs if signature != expected_signature { error!( "verify_rpc_signature: Invalid signature: secret {}, url {}, method {}, timestamp {}, signature {}, expected_signature {}", secret, url, method, timestamp, signature, expected_signature ); return Err(std::io::Error::other("Invalid signature")); } ``` This log line includes `secret` and `expected_signature`, both derived from the shared HMAC key. Any invalidly signed request triggers this path. The function is reachable from RPC and admin request handlers. ### PoC 1. Run RustFS with error loggi...

Nu Html Checker (validator.nu) contains a restriction bypass that allows remote attackers to make the server perform arbitrary HTTP/HTTPS requests to internal resources, including localhost services. While the validator implements hostname-based protections to block direct access to localhost and 127.0.0.1, these controls can be bypassed using DNS rebinding techniques or domains that resolve to loopback addresses.This issue affects The Nu Html Checker (vnu): latest (commit 23f090a11bab8d0d4e698f1ffc197a4fe226a9cd).

Livewire Filemanager, commonly used in Laravel applications, contains LivewireFilemanagerComponent.php, which does not perform file type and MIME validation, allowing for RCE through upload of a malicious php file that can then be executed via the /storage/ URL if a commonly performed setup process within Laravel applications has been completed.

Security professionals are moving up the executive ranks as enterprises face rising regulatory and compliance standards.

Cybersecurity researchers have discovered five new malicious Google Chrome web browser extensions that masquerade as human resources (HR) and enterprise resource planning (ERP) platforms like Workday, NetSuite, and SuccessFactors to take control of victim accounts. "The extensions work in concert to steal authentication tokens, block incident response capabilities, and enable complete account

Pacific Northwest National Labs' expert cybersecurity system, ALOHA, can recreate attacks and test them against organizations' infrastructure to bolster defense.

Researchers demonstrated WhisperPair, a set of attacks that can take control of many widely used Bluetooth earbuds and headphones without user interaction.
