## What is CVE-2026-87872?

CVE-2026-87872 is a medium-severity vulnerability in Red Hat Ceph Storage 5, published on 9 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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.

Weakness: CWE-295 (Improper Certificate Validation)

What it is: CVE-2026-87872 is a medium-severity vulnerability in Red Hat Ceph Storage 5, published on 9 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-87872 in the wild and no public exploit code.

Affected product: Red Hat Ceph Storage 5. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
