CVE-2025-46808: SUSE NeuVector Information Disclosure Flaw

CVE-2025-46808 Overview

CVE-2025-46808 is an information disclosure vulnerability in the SUSE NeuVector manager component. The flaw causes sensitive information to be written into the manager container's log file, where any actor with log access can read it. The issue is tracked under CWE-532: Insertion of Sensitive Information into Log File.

The vulnerability affects NeuVector versions prior to 5.4.5. Exploitation requires low-privilege authenticated access and some user interaction, but the scope changes because logged secrets can be consumed by downstream log aggregation systems and users beyond the manager container itself.

Critical Impact
Sensitive data written to the NeuVector manager log can be harvested by anyone with log-read access, enabling secondary attacks against the Kubernetes workloads NeuVector protects.

Affected Products

SUSE NeuVector manager versions before 5.4.5
NeuVector deployments running the vulnerable manager container image
Kubernetes clusters using NeuVector for runtime container security

Technical Details for CVE-2025-46808

Vulnerability Analysis

NeuVector is a Kubernetes-native container security platform maintained by SUSE. The manager component provides the web console and REST application programming interface (API) used to configure policies, view events, and manage the NeuVector controller.

The vulnerability stems from the manager writing sensitive values into its container log stream during normal operation. Any principal with permission to read manager container logs, including cluster operators, log-forwarder service accounts, and central logging platforms, can retrieve the exposed data. Because Kubernetes container logs are typically aggregated into external systems, the disclosure surface extends beyond the pod itself.

The attacker requires authenticated low-privilege access and some user interaction to trigger the logging behavior. Once the sensitive data reaches the log, the confidentiality impact is high while integrity and availability of the manager itself remain unaffected.

Root Cause

The root cause is improper handling of sensitive fields during log generation in the NeuVector manager code path. Instead of masking or omitting secrets, the affected versions serialize them into log records. See the GitHub Security Advisory GHSA-fggw-hv56-8m6r for the maintainer analysis.

Attack Vector

An authenticated user performs an action in the NeuVector manager that causes the sensitive payload to be logged. A separate actor with access to the manager container logs, whether through kubectl logs, a sidecar log shipper, or a downstream Security Information and Event Management (SIEM) system, reads the disclosed information. The exposed data can then be reused to escalate access to NeuVector-protected workloads or upstream systems.

See the SUSE Bug Report for CVE-2025-46808 for vendor-confirmed technical details.

Detection Methods for CVE-2025-46808

Indicators of Compromise

Presence of secret material, tokens, or credential fragments in NeuVector manager container logs.
Access to neuvector-manager-pod logs by service accounts or users outside the expected NeuVector operations team.
Log-forwarder queries or exports that specifically target the NeuVector manager namespace.

Detection Strategies

Scan archived NeuVector manager logs for patterns matching API keys, bearer tokens, and password fields.
Audit Kubernetes role-based access control (RBAC) bindings that grant pods/log verbs on the NeuVector namespace.
Correlate authentication actions in the NeuVector manager with subsequent log-read events to identify possible harvesting.

Monitoring Recommendations

Forward NeuVector manager logs into a dedicated, access-restricted index rather than a shared logging tier.
Alert on any principal reading NeuVector manager logs that is not part of an approved allowlist.
Rotate any credentials, tokens, or session material that may have been logged prior to upgrading.

How to Mitigate CVE-2025-46808

Immediate Actions Required

Upgrade the NeuVector manager to version 5.4.5 or later across all clusters.
Rotate credentials, API tokens, and secrets that were handled by the manager while running a vulnerable version.
Restrict Kubernetes RBAC so that only required accounts can read NeuVector manager pod logs.
Purge historical NeuVector manager logs from long-term storage after triage, or restrict access to them.

Patch Information

SUSE has fixed the issue in NeuVector 5.4.5. Refer to the GitHub Security Advisory GHSA-fggw-hv56-8m6r and the SUSE Bug Report for CVE-2025-46808 for the fixed image tags and release notes. Update the NeuVector Helm chart or operator to pull the patched manager image.

Workarounds

Limit pods/log permissions in the NeuVector namespace to a minimal set of operational accounts until the upgrade completes.
Route NeuVector manager logs to an isolated log store with encryption at rest and strict access controls.
Disable or reduce verbosity of non-essential logging in the manager where configuration allows, pending the upgrade.

bash

# Configuration example
# Restrict access to NeuVector manager logs via Kubernetes RBAC
kubectl -n neuvector get rolebindings,clusterrolebindings -o wide \
  | grep -Ei 'pods/log|view|edit|admin'

# Upgrade NeuVector via Helm to the patched release
helm repo update
helm upgrade neuvector neuvector/core \
  --namespace neuvector \
  --version 5.4.5
