CVE-2026-63131: OpenBao Skips Stricter Deny Policy for LIST operations
When a policy operator has written capabilities = ["deny"] on a path with a trailing wildcard but allowed a broader list operation (e.g., a deny on secrets/metadata/restricted/* but allowed list on secrets/metadata/*), OpenBao would incorrectly allow the operation. This did not impact other operation types.
