Audit-Version 2 Neueste
18. Aug. 2026, 08:34
Most scanner matches are documentation, tests, fixed imports, status constants, or expected local file operations. Confirmed risks include CAPTCHA circumvention, unrestricted authenticated fetching, arbitrary credential forwarding, command-line secret exposure, and unbounded direct downloads. No prompt injection text was found. Static review was capped at 400/766 representative findings; omitted static matches are unconfirmed, so automatic publishing stays disabled until manual review.

Automated CAPTCHA Circumvention
The skill detects CAPTCHA gaps and simulates human-like drags or checkbox clicks to defeat provider verification controls.
The implementation explicitly calculates CAPTCHA gaps, generates human-like movement, retries alternate profiles, and checks whether verification passed.
Hoch
API Key Forwarded to Arbitrary Endpoint
A configured IEEE endpoint accepts any URL, and the downloader appends the stored API key before sending the request.
The endpoint is stored without hostname validation, then converted to a URL and receives the API key as a query parameter.
Hoch

Unrestricted Authenticated URL Fetching
User-supplied URLs are fetched directly or inside an authenticated browser without scheme, hostname, or private-network restrictions.
The CLI accepts arbitrary URL strings and passes them to fetch or browser navigation without an allowlist or private-address check.
Hoch
Command-Line Secret Exposure
API keys and institutional tokens can be passed as command arguments, exposing them through shell history and process listings.
The parser defines API-key, insttoken, and authtoken arguments, and cmd_set stores those argument values as credentials.
Mittel
Unbounded Direct Download Buffering
Direct downloads buffer the entire response in memory before validation and writing, with no byte limit.
The response arrayBuffer is fully materialized before content checks, and this path has no Content-Length or streamed byte cap.
Mittel
Unrestricted CDP Proxy Destination
The CLI accepts any proxy URL and sends browser-control payloads to it without requiring loopback or explicit trust.
The proxy argument is only trimmed, then receives target identifiers, URLs, selectors, and generated browser JavaScript through HTTP requests.
Elemente der Fähigkeitsprüfung (7)
Dies sind echte lokale Fähigkeiten, die für diese Fähigkeit erwartet werden können; daher müssen sie überprüft werden, werden jedoch nicht als bestätigtes bösartiges Verhalten gezählt.
Hoch
Generic API/secret keys
api_key = args.api_key or os.environ.get("LIT_DL_API_KEY") or getpass.getpass("API key: ")
The API key may come from --api-key, exposing the secret through shell history and process arguments.
Hoch
Generic API/secret keys
set_cmd.add_argument("--api-key", help="Prefer the hidden prompt or LIT_DL_API_KEY over command-line
This defines a command-line API-key option, which exposes secrets to shell history and local process inspection.
Hoch
Fetch API call
const response = await fetch(pdfUrl, { headers: { Accept: "application/pdf, text/html, application/x
This fetches the user-supplied --pdf-url without protocol, hostname, or private-network validation.
Hoch
Fetch API call
const r = await fetch(${fetchTarget}, { credentials: "include" });
This fetches a supplied URL with credentials inside an authenticated browser context, creating an authenticated request and local-network access risk.
Hoch
Fetch API call
const js = `fetch('http://localhost:0/cdp',{
This request carries raw CDP mouse commands used to imitate human input and defeat verification controls.
Hoch
Fetch API call
const r=await fetch(${JSON.stringify(url)},{credentials:'include'});
This downloads a selected URL with browser credentials and transfers the response from the authenticated page into a local file.
Mittel
Fetch API call
const response = await fetch(url, {
This generic fetch sends browser-control requests to a configurable proxy URL without restricting the destination to a trusted local service.
