Severity

critical9.8

CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Fix status not established

No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

AutoBangumi versions before 3.2.8 have hard-coded default credentials, allowing unauthenticated attackers to gain full control. The weakness is due to the use of default credentials seeded at startup. Attackers can submit these credentials to the login endpoint to access the application.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

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.
