https://seclists.org/oss-sec/2026/q3/606: [CVE-2026-8715] HashiCorp Vault Sects Operator 1.3.0-1.4.1: tenant-controlled sectIDPath leaks operator ServiceAccount token (path to cluster-admin)

Q: Who can exploit this issue?

A tenant able to write the namespaced VaultAuth or VaultAuthGlobal resources can set secretIDPath and direct the Vault connection address to a listener they control. The operator then reads its own projected ServiceAccount token and sends it in the AppRole login request.

Q: What access does a stolen operator ServiceAccount token provide?

The leaked token can read and write Secrets in every namespace. It also has cluster-wide permission to create serviceaccounts/token resources, providing a path to cluster-admin access.

Q: Which releases require remediation?

HashiCorp Vault Secrets Operator versions 1.3.0 through 1.4.1 are affected. Version 1.5.0 is identified as the fixed release.
