AstrBotDevs AstrBot Vulnerability Leads to Hardcoded Credentials (CVE-2026-7579)

A critical security vulnerability, CVE-2026-7579, has been identified in AstrBotDevs AstrBot, affecting versions up to 4.16.0. The vulnerability lies within the Dashboard component, specifically in the astrbot/dashboard/routes/auth.py file. An unspecified processing flaw allows attackers to retrieve or leverage hardcoded credentials. The vulnerability can be exploited remotely and has been publicly disclosed, increasing the risk of exploitation. The vendor was notified, but did not respond to the disclosure. Successful exploitation could lead to unauthorized access to sensitive information or control over the AstrBot application.

Attack Chain

1. Attacker identifies a vulnerable AstrBot instance running a version up to 4.16.0.
2. Attacker sends a crafted request to the astrbot/dashboard/routes/auth.py endpoint.
3. The vulnerable code in auth.py processes the request improperly, exposing hardcoded credentials.
4. Attacker extracts the hardcoded credentials from the response.
5. Attacker uses the hardcoded credentials to authenticate to the AstrBot dashboard.
6. Attacker gains unauthorized access to administrative functions within the AstrBot application.
7. Attacker uses the compromised access to modify bot configurations or access user data.
8. Attacker leverages compromised bot to conduct malicious activity such as spam or data theft.

Impact

Successful exploitation of CVE-2026-7579 allows a remote attacker to obtain hardcoded credentials, leading to complete control over the AstrBot application. This can result in unauthorized access to sensitive data, modification of bot configurations, and potential misuse of the bot for malicious purposes. The lack of vendor response exacerbates the risk, leaving users vulnerable to potential attacks.

Recommendation

• Upgrade AstrBot to a patched version beyond 4.16.0 if a patch becomes available from AstrBotDevs to remediate CVE-2026-7579.
• Monitor web server logs for suspicious requests targeting the astrbot/dashboard/routes/auth.py endpoint as described in the Attack Chain.
• Deploy the Sigma rule detecting access to the vulnerable auth.py route to identify potential exploitation attempts.
• Implement strong authentication and authorization mechanisms to protect the AstrBot dashboard, mitigating the impact of hardcoded credentials.
