What is CVE-2026-127075?

OpsTree BuildPiper versions earlier than 2.7.0 are susceptible to a path traversal vulnerability. This flaw enables authenticated users to manipulate file paths using traversal sequences, such as ../../../../etc/passwd, thereby gaining unauthorized access to arbitrary files. Consequently, sensitive configuration files and service-account tokens may be exposed within generated manifests and logs, posing significant security risks to the affected systems.

Affected Version(s)

BuildPiper 0 < 2.7.0

Exploit Proof of Concept (PoC)
