# Meteroid: API token lookup leaks other tenants' secret hashes

Link for people: https://infrastack.ai/live/CVE-2026-125751 (this .md is for agents)

Meteroid before 2.2.0 has a gRPC handler, GetApiTokenById, that does not check the caller's tenant. A signed-in user with settings:read permission can request another tenant's API token ID and receive that token's Argon2 secret hash and owning tenant ID.

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

## How to check

- Check the Meteroid version you run; the sources say versions before `2.2.0` are affected.

## Fix

- Move to Meteroid `2.2.0` or later.

- [fix] Release notes: github.com https://github.com/meteroid-oss/meteroid/releases/tag/v2.2.0

## From the sources

Meteroid before 2.2.0 contains an authorization bypass vulnerability in the ApiTokensService GetApiTokenById gRPC handler that fails to apply the caller's tenant context. Authenticated users with settings:read permission can supply another tenant's API token ID to obtain its Argon2 secret hash and owning tenant ID.
