Also, just a reminder... Revan is a Jedi, and, even if he did know those powers, he wouldn't use them.
Revan was the one who trained Malak in the ways of the Sith and Malak himself acknowledged this fact. Malak would follow Revan in various worlds that contained secrets of Sith knowledge like a loyal companion and apprentice. Still Revan's knowledge was stated to be greater then that of Malak's for a reason.
After a couple of years, Malak indeed became very powerful but he was not powerful enough to challenge Darth Revan and yet got the title of DLOTS through betrayal. And after becoming DLOTS, Malak wasn't exploring ancient Sith worlds for more knowledge but was more interested in finding Bastilla.
Malak indeed was also exploring the secrets of Star Forge but it was already operational in Revan's time. And Revan too understood Star Forge very well but his aims & plans were different and Malak assumed that Revan was not using Star Forge like he should, so he might not know much about it. But Malak's assumption was totally wrong as Revan was smart enough to make Star Forge operational and avoid the possibilities of being consumed by it as well (because Star Forge was known to consume those who tried to explore its secrets).
Star Forge did enhanced Malak's power (but Malak was too much over-confident about SF priorities and risked something even greater: his personal conciousness) and still what he knew was not enough to defeat Revan so you can assume the reason behind it.
