Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Scratch-Coding-Hut.github.io is the website for Coding Hut. The website as of 28 February 2025 contained a sign in with scratch username and password form. Any user who used the sign in page would be susceptible to any other user signing into their account. As of time of publication, a fix is not available but work on a fix is underway. As a workaround, users should avoid signing in.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The sign-in page on Scratch-Coding-Hut.github.io contains a vulnerability in its authentication mechanism that allows any user who signs in to have their account accessed by other users. This appears to be a session management or authentication bypass flaw where user credentials/sessions are not properly secured.

MitigationUsers should avoid signing in until a fix is implemented. The website operator needs to implement proper session management, secure authentication flows, and ensure user sessions are uniquely and securely handled to prevent unauthorized account access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify you are accessing the affected website
    Confirm that the URL in your browser is Scratch-Coding-Hut.github.io or any subdomain of this domain
    Affected if Your browser is pointed to Scratch-Coding-Hut.github.io and you use its sign-in page
  2. Identify if you have an account on this site
    Check whether you have registered or created an account on Scratch-Coding-Hut.github.io
    Affected if You have an account registered on this website
  3. Test session isolation after signing in
    Sign into your account, then open an incognito/private window and sign in with a different account. Attempt to access the first account's session or data to see if session cookies or tokens are shared between users
    Affected if You can access another user's account or their session by simply signing into the site in a different browser context
  4. Inspect browser cookies after authentication
    After signing in, open developer tools (F12) and examine the cookies for the domain. Check if session tokens are predictable, shared across users, or if authentication cookies lack proper isolation
    Affected if Session cookies are missing secure flags, are shared, or use predictable/sequential identifiers instead of unique random tokens

You are affected if you use Scratch-Coding-Hut.github.io and sign in, as the flawed session management allows other users to access your account.
