CVE-2026-54725 is a server-side request forgery vulnerability in bank-vaults vault-secrets-webhook prior to version 1.23.1. The webhook, which performs secret injection for Kubernetes workloads, accepts a user-controlled Vault address through annotation parsing in parseVaultConfig() and subsequently uses that address when creating a Vault client during mutation flows. In the affected code path, annotation-controlled configuration can direct the webhook to connect to an attacker-controlled Vault endpoint. When combined with the service account selection annotation, this can cause the webhook to transmit a Kubernetes ServiceAccount JWT to that attacker-controlled endpoint. The flaw therefore allows untrusted annotation input to influence outbound server-side connections and exfiltrate authentication material.
