CVE-2026-59388 · Severity: medium · CVSS 6.5 · Published 2026-10-30

Cloud Foundry's Cloud Controller (CAPI), which manages application deployments and services, leaks sensitive credentials into audit logs where they can be accessed by users with audit log permissions. Exposed secrets include custom buildpack credentials, syslog drain URLs, and service binding parameters, which could allow attackers or authorized users to gain unauthorized access to integrated services and infrastructure.

## How to fix

- Fixed in CAPI v1.249.0 or greater; cf-deployment v60.11.0 or greater

## Technical details

The Cloud Controller fails to redact sensitive data before writing audit events, exposing buildpack credentials in app manifest/create/update events, syslog drain URL credentials in user-provided service instance events, and service binding parameters in manifest and binding events. The vulnerability requires authentication and network access to view audit logs. An attacker with audit log access can extract credentials to compromise connected services.

## Affected products

- Cloud Foundry Foundation Cloud Controller (CAPI) up to v1.248.0
- Cloud Foundry Foundation cf-deployment before v60.11.0

## Timeline

- 2026-10-20: disclosed
