Overview
Affected versions of this package are vulnerable to Incorrect Authorization through the AllowOperation path-matching logic in vault/policy/acl.go. An attacker can perform an unauthorized LIST request on a more specific trailing-wildcard path by sending a request that matches a broader allowed list rule on a parent path, causing a capabilities = ["deny"] rule on the nested path to be ignored. This affects LIST operations on paths such as foo/metadata/private/* when a parent rule like foo/metadata/* grants list, allowing access to directory listings that the policy operator intended to block. Other operation types are not affected.
