  The presence of planets or sub-stellar objects still embedded in their native
protoplanetary disks is indirectly suggested by disk sub-structures like gaps,
cavities, and spirals. However, these companions are rarely detected. We
present VLT/NACO high-contrast images in $J$, $H$, $K_S$, and $L^{\prime}$ band
of the young star [BHB2007]-1 probing the inclined disk in scattered light and
revealing the probable presence of a companion. The point source is detected in
the $L^{\prime}$ band in spatial correspondence with complementary VLA
observations. This object is constrained to have a mass in the range of 37-47
M$_{Jup}$ and is located at 50 au from the central star, inside the 70 au-large
disk cavity recently imaged by ALMA, that is absent from our NACO data (down to
20 au). This mass range is compatible with the upper end derived from the size
of the ALMA cavity. The NIR disk brightness is highly asymmetric around the
minor axis, with the southern side 5.5 times brighter than the northern side.
The constant amount of asymmetry across all wavelengths suggests that it is due
to a shadow cast by a misaligned inner disk. The massive companion that we
detect could, in principle, explain the possible disk misalignment, as well as
the different cavity sizes inferred by the NACO and ALMA observations. The
confirmation and characterization of the companion is entrusted to future
observations.
