Scoped Vulnerability Tracking

Database

The most urgent threat is a critical unauthenticated SQL injection vulnerability in Metacat (CVE-2026-48528) that allows for full data exfiltration and compromise of the underlying PostgreSQL database. Additionally, multiple high-severity vulnerabilities in MySQL and PostgreSQL require immediate attention, including a potential privilege escalation in MySQL via the Data Science Pipelines Operator and a client-side denial of service in the pgjdbc driver.

Formal Vulnerabilities

PostgreSQL — CVE-2026-48528 (CVSS 9.8 CRITICAL)

Summary: An unauthenticated SQL injection vulnerability exists in Metacat's REST API endpoints (`/cn/v1/object` and `/cn/v2/object`) due to unsanitized `nodeId` parameters. Attackers can use error-based techniques to extract arbitrary data or execute arbitrary SQL statements to modify or delete database contents.

Affected Features / Interoperability: Impacts the Metacat data repository software; specifically, the `/cn` REST API endpoints.

The most urgent issue is CVE-2026-14450 in Red Hat's MaaS API, a critical flaw allowing any pod in the cluster to bypass Kuadrant AuthPolicy gateway by forging HTTP headers, enabling unauthorized access, privilege escalation, and cross-tenant ServiceAccount token minting. This vulnerability is actively exploited in the wild according to CISA KEV, making immediate remediation a top priority.

Formal Vulnerabilities

Kubernetes — CVE-2026-14450 (CVSS 9.9 CRITICAL) 🔴 ACTIVELY EXPLOITED (CISA KEV)

Summary: A flaw in the MaaS API allows any pod within the cluster to bypass the Kuadrant AuthPolicy gateway by forging HTTP headers (`X-MaaS-Username` and `X-MaaS-Group`), which are trusted verbatim. This lack of first-party authentication enables an attacker to gain unauthorized access and escalate privileges, including minting Kubernetes ServiceAccount tokens in other tenants' namespaces, revoking API keys, and exfiltrating sensitive model access configuration.

Affected Features / Interoperability: Impacts the MaaS API and Kuadrant AuthPolicy gateway. Downstream effects include unauthorized access to tenant namespaces, compromised ServiceAccount tokens, and potential exposure of model access configurations.

Actions:

Kubernetes — CVE-2026-8715 (CVSS 9.6 CRITICAL)

Summary: Vault Secrets Operator versions 1.3.0 up to 1.4.1 are vulnerable to arbitrary file read and credential exfiltration via AppRole authentication configuration, allowing a tenant with limited Kubernetes RBAC permissions to read files from the operator pod's filesystem and transmit their contents to a tenant-controlled endpoint, potentially leading to privilege escalation.

Actions:

Kubernetes — CVE-2026-18951 (CVSS 8.8 HIGH)

Summary: The Red Hat OpenShift AI (RHOAI) overlay for the training operator incorrectly aggregates `trainjobs` management permissions into the native Kubernetes `edit ClusterRole`, allowing any user with `edit ClusterRole` permissions in a namespace to create, modify, and delete `TrainJobs`. Combined with unrestricted PodTemplateSpec passthrough, this can lead to privilege escalation and arbitrary code execution.

Affected Features / Interoperability: Affects RHOAI training operator and Kubernetes RBAC. Impacts TrainJob management, service account impersonation, and pod configuration controls.

Source:

Actions:

Kubernetes — CVE-2026-18982 (CVSS 8.8 HIGH)
