What is CVE-2026-111693?

DataBuff ai-apm-web versions up to 0.1.10 are susceptible to a vulnerability that exposes hard-coded default credentials. This security flaw enables unauthenticated attackers to gain administrative access by utilizing the built-in credentials for the admin account (admin/Databuff@123). By sending a POST request with these credentials to the /webapi/api/v1/auth/login endpoint, attackers can retrieve an administrator token, granting them access to all secured API routes. Users must take immediate action to mitigate potential risks associated with this vulnerability.
