Tooling: Files or Directories Accessible to External Parties
CVE-2026-8715 is a critical-severity files or directories accessible to external parties vulnerability in Tooling from HashiCorp, with a CVSS 3.1 base score of 9.6 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 1.5.0 as the first without the flaw, so updating Tooling to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.47% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description
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.
