CVE-2026-55100

hashi-vault-js is a Node.js module for interacting with the HashiCorp Vault API. Prior to 0.5.2, src/Vault.js concatenates unencoded identifier values including name, username, group, role, and version into Vault request paths and query strings instead of using encodeURIComponent() and URLSearchParams, allowing path traversal and query parameter injection. This issue is fixed in version 0.5.2.
