Summary

CVE-2026-58466 is a critical-severity Use of Default Credentials (CWE-1392) vulnerability. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Default Accounts (T1078.001); ranked at the 41th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure configuration settings establish baselines that prohibit default credentials on system components.

IA-5 Authenticator Management good match

Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.

RA-5 Vulnerability Monitoring and Scanning good match

Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.

AC-2 Account Management partial match

Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.

PR.PS-01 full match
prevents

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.

PR.AA-01 mostly match
prevents

Credential management processes directly require replacing or disabling default passwords and keys.

PR.AA-03 partial match
prevents

Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.9 Configuration management mostly match
prevents

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
