Vulnerability in Red Hat Ceph Storage 5
CVE-2026-87872
A flaw was found in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection. The shared OCAPI request helper disables TLS certificate validation on every request and the modules expose no parameter to re-enable it, while sending HTTP Basic-Auth credentials to an https endpoint. An attacker positioned on the network path between the Ansible controller and the OCAPI-managed storage/enclosure device can present any certificate, intercept the session, capture the credentials, and tamper with responses.
