## Summary `Rack::Multipart::Parser` buffers the entire multipart **preamble** (bytes before the first boundary) in memory without any size limit. A client can send a large preamble followed by a valid boundary, causing significant memory use and potential process termination due to out-of-memory (OOM) conditions. ## Details While searching for the first boundary, the parser appends incoming data into a shared buffer (`@sbuf.concat(content)`) and scans for the boundary pattern: ```ruby @sbuf.scan_until(@body_regex) ``` If the boundary is not yet found, the parser continues buffering data indefinitely. There is no trimming or size cap on the preamble, allowing attackers to send arbitrary amounts of data before the first boundary. ## Impact Remote attackers can trigger large transient memory spikes by including a long preamble in multipart/form-data requests. The impact scales with allowed request sizes and concurrency, potentially causing worker crashes or severe slowdown due to ...

The leak exposed the names, Social Security numbers, and health details of more than 90,000 military patients, troops, veterans, and their families.

Cybersecurity researchers have charted the evolution of XWorm malware, turning it into a versatile tool for supporting a wide range of malicious actions on compromised hosts. "XWorm's modular design is built around a core client and an array of specialized components known as plugins," Trellix researchers Niranjan Hegde and Sijo Jacob said in an analysis published last week. "These plugins are

Versions of the package pdfmake before 0.3.0-beta.17 are vulnerable to Allocation of Resources Without Limits or Throttling via repeatedly redirect URL in file embedding. An attacker can cause the application to crash or become unresponsive by providing crafted input that triggers this condition.

CrowdStrike on Monday said it's attributing the exploitation of a recently disclosed security flaw in Oracle E-Business Suite with moderate confidence to a threat actor it tracks as Graceful Spider (aka Cl0p), and that the first known exploitation occurred on August 9, 2025. The exploitation involves the exploitation of CVE-2025-61882 (CVSS score: 9.8), a critical vulnerability that facilitates

### Summary The web UI for SillyTavern is susceptible to DNS rebinding, allowing attackers to perform actions like install malicious extensions, read chats, inject arbitrary HTML for phishing, etc. ### Details DNS rebinding is a method to bypass the CORS policies by tricking the browser into resolving something like `127.0.0.1` for a site's DNS address. This allows anybody to get remote access to anyone's SillyTavern instance **without** it being exposed, just by visiting a website. ### PoC 1. Host the PoC HTML file on a `/rebind.html` endpoint (or any other endpoint) on a web server on port 8000 2. Go to https://lock.cmpxchg8b.com/rebinder.html and input your IP address (A) to rebind to 127.0.0.1 (B) 3. Replace the URL in the HTML with the returned URL on the site 4. Go to `http://[URL]:8000/rebind.html` in firefox or on any mobile browser if you're using termux 5. Check the developer tools console. It should return all of the data Here is the PoC code: ```html <!DOCTYPE html> <...
