CVE-2026-57867 MicroRealEstate CVE debrief

CVE-2026-57867 is a high-severity vulnerability in MicroRealEstate that allows attackers to bypass authentication. This issue arises from a lack of token state management, enabling adversaries to brute-force One-Time Passwords (OTP) and log in as any user. The vulnerability affects MicroRealEstate versions up to 1.0.0-alpha3. To address this vulnerability, security teams and administrators should be aware of the potential risks and take immediate action to assess and mitigate them. The CVSS score of 8.8 indicates a high severity, and the lack of token state management makes it possible for attackers to exploit this vulnerability. It is essential to review and update MicroRealEstate to a version beyond 1.0.0-alpha3 if possible and implement additional authentication mechanisms to supplement existing OTP systems.
