Critical severity, CVSS 9.6. EPSS: 0.5% chance of exploitation in the next 30 days.

Vault Secrets Operator 1.3.0 up to 1.4.1 is vulnerable to an arbitrary file read and credential exfiltration issue in the AppRole authentication configuration that may allow 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 within the cluster. This vulnerability (CVE-2026-8715) is fixed in Vault Secrets Operator 1.5.0.

Affected products

• Hashicorp Tooling: from 1.3.0, before 1.5.0 (fixed in 1.5.0)
