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 vulnerability in EstrellaXD's Auto_Bangumi product before version 3.2.8. The issue arises from hard-coded default credentials inserted at startup via the add_default_user() function in the database user module when 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 to the Auto_Bangumi application without authentication. This includes the ability to modify RSS feed settings, downloader configurations, and access all authenticated API endpoints, potentially leading to complete compromise of the application and its data.
Mitigation Recommendations
No official patch or remediation level is currently confirmed. Users should upgrade to version 3.2.8 or later once available, as this version is indicated as the fixed release. Until then, restrict access to the application to trusted networks and monitor for unauthorized access attempts. Check the vendor advisory for updates on official fixes.
