Advisory · CVE-2026-74037

Revoked Wazuh run_as tokens were not invalidated

Wazuh manager 4.0.0 through the releases before 4.14.8 did not properly invalidate revoked run_as tokens, so a former administrator's token may keep working. VulnCheck rates it CVSS 4.0 8.6.

Explain it like I’m five

Firing the admin does not fire their token: revoked credentials stayed valid, so yesterday's access quietly remains today's access.

SIMPLIFIED_ATTACK_PATH03 STEPS
  1. 01Admin token issued

    An administrator holds a run_as token for the Wazuh manager.

  2. 02Access revoked

    The administrator's access is revoked, but the token is not invalidated.

  3. 03Token still works

    The old token continues to authenticate with privileged effect.

What happened

Wazuh disclosed CVE-2026-74037 for the manager in releases 4.0.0 through those before 4.14.8. Revoked run_as tokens were not invalidated by the token-checking path, which can let a former administrator retain privileged access.

The vendor’s affected data marks 4.14.8 as the first unaffected release, so upgrading to 4.14.8 or later is the stated fix.

What to do

  1. Inventory every Wazuh manager deployment, including test, training, and individually managed instances.
  2. Apply the vendor fix or upgrade exactly as directed in the linked vendor bulletin or advisory.
  3. Restrict network access to Wazuh manager while remediation is underway, especially for internet-facing instances.
  4. Review application and server logs for successful run_as authentication for accounts that were disabled or removed, and tokens used from new locations.
  5. Check for accounts, content, or configuration created outside normal change processes, and rotate exposed credentials where access cannot be ruled out.
  6. Verify the deployed version or patch level after remediation.

Management note

Credential revocation that does not revoke is an offboarding failure with a CVE number. Upgrade, then force-rotate manager tokens for departed admins.
