I don't think NASA specifically looking for a specific object (i.e., Nibiru). I think they see the WISE as a funded way to look for a certain class of asteroids that may be hard to detect -- especially since they see shortcomings in they're current funding for the search for killer asteroids.
They know the program funding has shortcomings, and the WISE spacecraft will help ease those shortcomings by searching for a whole class of objects that can't easily be seen using conventional means -- thus easing the burden on the $800,000,000 killer asteroid program.
It seems pretty straightforward (and non-conspiratorial) to me.
The United States is currently the only country with an active, government-sponsored effort to detect and track potentially hazardous near-Earth objects (NEOs).
Congress has more recently mandated that by 2020 NASA should detect and track 90 percent of NEOs that are 140 meters (0.14 kilometers) in diameter or larger, a category of objects that is generally recognized to represent a very significant threat to life on earth. Achieving this goal may require the building of one or more additional observatories, possibly including a space-based observatory.
NASA has funded an enhancement to the baseline WISE mission, called NEOWISE, to facilitate solar system science. NEOWISE is expected to discover hundreds of new NEOs with sizes as small as ~100 meters. The advantage of an infrared-selected sample is that it is inherently less biased against discovery of low-albedo objects than are optical surveys. However, NEOWISE is not a stand-alone NEO survey and requires coordination with other surveys to make full use of its data.
WISE Mapping the Infrared Sky
WISE will:
■ Find the most luminous galaxies in the Universe.
■ Find the closest stars to the Sun.
■ Detect most Main Belt asteroids larger than 3 km (3,000 meters).
■ Enable a wide variety of studies ranging from
the evolution of planetary debris discs to the history
of star formation in normal galaxies.
■ Provide an important source catalog for JWST.

Obviously they think there is a good chance these "dark asteroids" may pose a threat, hence the use of WISE. However, I don't think they KNOW a specific body object (such as Nibiru, as you say) is out there.
...and I don't think that just because NASA has funded the WISE project while the asteroid people say their funding is inadequate means that NASA must already know something....
What about all of the other projects that NASA is funding? Some people could argue that NO projects are a higher priority than looking for killer asteroids, so why are you picking out THIS particular project as the one that proves that NASA knows something about a specific rogue object that they are not telling us. There are many projects that are more adequately funded than the killer asteroid project.
It seems to me that the asteroid people need to state their case better so they could receive more funding from congress -- or they should have adequately stated their case for a bigger budget instead of the original $800,000,000 budget in the first place.

Definitions don't often include the connotations of words. My impression is that the world "admit" connotes a previous denial. Going strictly by the definition "admits the possibility" is redundant. "afforded possibility of the possibility".
The article only says that Proxima is our closet neighbor. It doesn't say what kind of star it is.
(I know, not really important. But I just couldn't let it go.)

...all I'm saying is that NASA isn't admitting that a brown dwarf star exists within the confines of our solar system and they certainly are not admitting that one is on an orbital approach to Earth (such as the Nibiru story goes).
And that is the same stance I have. I do not believe that NASA has secret knowledge of a brown dwarf in our solar system. But they are looking for a reason. Why else mention that in the article referenced in the OP?

It's one thing to say these things may exist, but it's a totally different thing to say that they could be the mythical Nibiru.
NASA transferred funding from an already vastly-underfunded program (the NEO asteroid program) which experts (National Academy of Sciences) and Congress say “represent a very significant threat to life on earth” to a new program (the WISE program) which states as one of it’s objectives “uncover the coldest stars, called brown dwarfs, perhaps even one closer to us than our closest known neighbor”. The WISE program doesn't even contribute to the identification of asteroids in the NEO program even though that's how NASA justified transferring funds from NEO to WISE. In fact, WISE can't identify objects small than 3,000 meters.
Why would they transfer the funding to WISE from the NEO program? Do they think that finding a brown dwarf even closer to us than our closest known neighbor is more important than finding the near earth objects (representing a very significant threat to life on earth)? Yes, they do.

That is not a planet. It is debris. It appears only in that image, not in the one before, nor in the one after.
It has been discussed before.

WISE was not downgraded. It will be able to detect asteroids as small as 100 meters. Some of them. It will be able to detect most of the asteroids which are larger than 3 km.
It was never going to be able to find most of the small asteroids. I'm glad it will be able to find most of the large ones. I'm also glad it will be able to find some of the smaller ones.
The fact sheet says
"discover hundreds of new NEOs with sizes as small as ~100 meters."
"Detect most Main Belt asteroids larger than 3 km (3,000 meters).

SOHO does not filter moving objects. Debris comes from the satellite itself and can also be random particles in space.
SOHO debris
Please keep your expectations to yourself.

From your sources.
The interim report says that WISE will
The fact sheet says
"discover hundreds of new NEOs with sizes as small as ~100 meters."
"Detect most Main Belt asteroids larger than 3 km (3,000 meters).
It will find hundreds of small ones and most of the big ones.
The survey will help search for the origins of planets, stars, and galaxies and create an infrared atlas whose legacy will endure for decades.
WISE will:
■ Find the most luminous galaxies in the Universe.
■ Find the closest stars to the Sun.
■ Detect most Main Belt asteroids larger than 3 km.
■ Enable a wide variety of studies ranging from
the evolution of planetary debris discs to the history
of star formation in normal galaxies.
■ Provide an important source catalog for JWST.
Something along the lines of: Detect most asteroids larger than 0.15 km. But they didn't, did they... why not?
t is unacceptable to state as a fact that "It will be able to detect asteroids as small as 100 meters. Some of them. It will be able to detect most of the asteroids which are larger than 3 km." You don't know this and they certainly did not say this.
