CVE-2026-8715: CWE-552: Files or Directories Accessible to External Parties in HashiCorp Tooling
Vault Secrets Operator versions 1.3.0 through 1.4.1 contain a vulnerability in the AppRole authentication configuration that allows tenants with limited Kubernetes RBAC permissions to read arbitrary files from the operator pod's filesystem and exfiltrate credentials. This can lead to privilege escalation within the Kubernetes cluster. The issue is fixed in version 1.5.0.
AI Analysis
Technical Summary
CVE-2026-8715 is a critical vulnerability (CWE-552) affecting Vault Secrets Operator versions >=1.3.0 and <1.5.0. It allows a tenant with limited Kubernetes RBAC permissions to exploit the AppRole authentication configuration to read arbitrary files from the operator pod's filesystem and transmit their contents to an attacker-controlled endpoint. This arbitrary file read and credential exfiltration can lead to privilege escalation within the cluster. The vulnerability is resolved in Vault Secrets Operator 1.5.0.
Potential Impact
An attacker with limited Kubernetes RBAC permissions can read sensitive files from the operator pod's filesystem and exfiltrate credentials, potentially escalating privileges within the cluster. This compromises confidentiality and integrity of secrets managed by the Vault Secrets Operator.
Mitigation Recommendations
Upgrade Vault Secrets Operator to version 1.5.0 or later, where this vulnerability is fixed. No other mitigations are specified in the vendor advisory.
