github.com/hashicorp/nomad is vulnerable to Authorization Bypass Through User-Controlled Key
67
Medium Risk
This Affects:
github.com/hashicorp/nomadTL;DR
Affected versions of this package are vulnerable to unauthorized information disclosure due to flawed task naming validation. By naming a task “alloc,” an attacker could exploit filesystem directory naming consistency and gain access to another task’s directory within the same allocation, thereby bypassing isolation. The fix prohibits “alloc” as a task name and rejects job submissions using it.
