Reply to comment by Christineblankie in Leaking window, mold in drywall behind peeled paint by Christineblankie

Check the exterior of the window carefully, on the sill, edges of the sill, and where the window meets the siding and caulk with silicone caulk. If done right, that should be a passable fix to get you through the winter. Post pictures back here if need be.

For the drywall, you should remove it and patch it with a new piece. I can’t speak to any concerns about the moisture barrier though.

Only thing I can add to caulking, be careful on the outside of the window frame when you close it (not the window part that opens and closes, the frame itself), there are usually little weep holes that allow water to drain out of the window casing and back outside. If someone installed them wrong and caulked over the holes or they're clogged the water can backup and seep back inside
