What is CVE-2026-127079?

The OpsTree BuildPiper product prior to version 2.7.0 is vulnerable due to the absence of rate limiting on the OTP verification process during password resets. This flaw allows attackers to exploit the system by initiating a password reset and submitting unchecked guesses at the 6-digit OTP, which could lead to unauthorized account access. This vulnerability poses a significant security risk, emphasizing the need for enhanced verification controls to prevent brute-force attacks.
