# OpsTree BuildPiper: authenticated users can build other projects' private Git repos

Link for people: https://infrastack.ai/live/CVE-2026-127076 (this .md is for agents)

OpsTree BuildPiper before 2.7.0 has a broken access control flaw that lets any logged-in user list Git repositories belonging to other projects. An attacker can then trigger builds from those repositories and read their source code, manifests and committed secrets.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm the BuildPiper version in use; versions before `2.7.0` are affected.
- Check whether user accounts that are not members of every project can call `GET /api/v1/git_repo/?all=true`.

## Fix

- OpsTree BuildPiper: `2.7.0` or later, per the advisory description.

## Timeline

- 2026-11-13T10:47:28+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-127076

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/opstree-buildpiper-before-2.7.0-broken-access-control-via-git-repo-api

## From the sources

OpsTree BuildPiper before 2.7.0 contains a broken access control vulnerability that allows authenticated users to list and build from Git repositories restricted to other projects. Attackers can enumerate repositories via GET /api/v1/git_repo/?all=true and submit any git_repo_id to the ci endpoint, cloning other projects' source code, manifests, and committed secrets.
