Simple, per-component application of RGB curves (as I presume is done by the base curve module) affects saturation. Imagine you have a colour with R=200, G=200, B=100. If you apply the usual S-shaped curve, it'll push the 200 values up, the 100 value down, which will increase brightness and saturation, too. In RawTherapee, there are multiple ways the RGB curves can be applied: 50.87.144.65/~rt/w/index.php?title=Exposure#Curve_Mode (if the IP changes, http://rawpedia.rawtherapee.com -> 1.3.1 Exposure Tab -> Exposure -> 13 Curve Mode).
If I recall correctly, the recommended best practice was a Weighted curve to darken the image (more punchy shadows) followed by a film-mode curve for highlights.
