CVE-2026-58466: Use of Default Credentials in EstrellaXD Auto_Bangumi
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.
AI Analysis
Technical Summary
CVE-2026-58466 is a critical authentication bypass vulnerability in EstrellaXD's Auto_Bangumi product before version 3.2.8. The vulnerability arises from hard-coded default credentials inserted by the add_default_user() function during initial database setup if the users table is empty. Attackers can exploit this by submitting these default credentials to the authentication login endpoint without prior authentication, thereby gaining administrative privileges and full control over the application’s configuration and API.
Potential Impact
An attacker can gain full administrative access without authentication, allowing them to modify RSS feed settings, downloader configurations, and interact with all authenticated API endpoints. This compromises confidentiality, integrity, and availability of the application and its data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should ensure the users table is not empty after installation or change default credentials immediately if possible. Monitor vendor communications for updates on patches or official mitigations.
