CVE-2026-87872: Improper Certificate Validation in Red Hat Red Hat Ceph Storage 5
CVE-2026-87872 is a vulnerability in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection used with Red Hat Ceph Storage 5. The modules disable TLS certificate validation on every request and do not provide an option to enable it, while sending HTTP Basic-Auth credentials to an HTTPS endpoint. This allows an attacker with network access between the Ansible controller and the OCAPI-managed device to intercept and tamper with communications and capture credentials.
AI Analysis
Technical Summary
The vulnerability exists in the OCAPI modules of the community.general Ansible collection, which are used to manage Red Hat Ceph Storage 5 devices. The shared OCAPI request helper disables TLS certificate validation (validate_certs=False) with no override option, exposing HTTP Basic-Auth credentials sent over HTTPS to interception. An attacker positioned on the network path can present any certificate, perform a man-in-the-middle attack, capture credentials, and tamper with responses. This issue affects community.general content, which is community-maintained and not shipped in Red Hat-supported execution environments or RHEL AppStream. Exploitation requires an on-path network position between the Ansible controller and the managed device.
Potential Impact
An attacker with network access between the Ansible controller and the OCAPI-managed device can intercept and manipulate communications by presenting arbitrary TLS certificates, leading to credential disclosure and response tampering. The vulnerability impacts confidentiality and integrity but does not affect availability. The CVSS v3.1 score is 6.8 (medium severity) with high confidentiality and integrity impact, high attack complexity, and no privileges or user interaction required.
Mitigation Recommendations
No official fix or patch is currently available. Until a fix is released, Red Hat recommends running the OCAPI modules only over fully trusted and isolated management network paths without untrusted on-path segments. Treat the OCAPI Basic-Auth credentials as exposed in transit and rotate them if man-in-the-middle exposure is suspected. Monitor the vendor advisory for updates on patch availability.
