# HashiCorp Vault: integrated storage join can leak server environment credentials

Link for people: https://infrastack.ai/live/CVE-2026-92735 (this .md is for agents)

A new, uninitialized Vault node can be made to send credentials from its server environment to an attacker-controlled server during the integrated storage join process. An unauthenticated attacker with network access to that node can trigger it.

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

## How to check

- Run `vault version` on each Vault server and compare against the fixed versions.
- Check whether any Vault node is new and uninitialized and reachable from untrusted networks.

## Fix

- Vault Community Edition: `2.2.2`
- Vault Enterprise: `2.2.2`, `1.21.14`, `1.19.25`

## From the sources

HashiCorp Vault and Vault Enterprise are vulnerable to an issue in the integrated storage join process that may allow an unauthenticated attacker with network access to a new, uninitialized node to cause that node to send credentials from its server environment to an attacker-controlled server. This vulnerability (CVE-2026-92735) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.25.
