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
AutoBangumi before 3.2.8 contains a hard-coded default credentials vulnerability that allows unauthenticated attackers to authenticate as the administrator by using the publicly known default credentials seeded at startup via add_default_user() in the database user module when the users table is empty. Attackers can submit the default credentials to the authentication login endpoint to gain full control of the application, including RSS feed configuration, downloader configuration, and all authenticated API endpoints.

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 · high confidence

AutoBangumi before 3.2.8 creates hard-coded default administrator credentials via add_default_user() when the users table is empty. Attackers with knowledge of these publicly seeded credentials can authenticate to the login endpoint and gain full administrative control over RSS feed configurations, downloader settings, and all authenticated API endpoints.

MitigationUpgrade to version 3.2.8 or later which should remove the hard-coded default credential seeding. Verify that any existing deployment does not have default credentials in use and force a credential reset if the system was previously vulnerable.

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. Identify installed AutoBangumi version
    Check the application version file, Docker image tag, or running service version (e.g., docker ps, pip show autobangumi, or the web UI about page)
    Affected if version is lower than 3.2.8 (e.g., 3.2.7, 3.2.6, etc.)
  2. Inspect database users table state
    Access the SQLite/database file used by AutoBangumi and query the users table: SELECT * FROM users; or check if the table is empty
    Affected if the users table exists but contains no rows (is empty), or contains a user account created by default with predictable credentials
  3. Verify default credential presence
    Examine the database user records for accounts with default usernames (commonly 'admin', 'root', or similar) that may have been auto-created on first startup when no users existed
    Affected if a default administrator account exists that was auto-generated on initial setup
  4. Check login endpoint accessibility
    Confirm the AutoBangumi web interface login endpoint is network-accessible (e.g., curl http://target:7899/login or similar port the service runs on)
    Affected if the login endpoint is exposed to untrusted networks without authentication barriers

You are affected if AutoBangumi version is below 3.2.8 AND the users table is empty or contains a default auto-generated administrator account, especially if the login endpoint is network-accessible.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Interim mitigation

Upgrade to version 3.2.8 or later which should remove the hard-coded default credential seeding. Verify that any existing deployment does not have default credentials in use and force a credential reset if the system was previously vulnerable.

Recommended fix High confidence

AutoBangumi version 3.2.8

  1. Back up your current AutoBangumi installation and database before upgrading.
  2. Upgrade AutoBangumi to version 3.2.8 or later where the hard-coded default credentials vulnerability is fixed.
  3. After upgrading, verify that the add_default_user() function no longer seeds hard-coded credentials in an insecure manner.
  4. If you previously used default credentials or suspect compromise, create new administrator accounts with strong, unique passwords and delete any unauthorized accounts.
  5. Review application logs for any unauthorized access attempts using default credentials.
