From what I know, PolyMC and other launchers pull libraries needed to run the game when first setting up new instances and also periodically update those. Even if you don't update PolyMC, these libraries could be updated by the owner, replaced with versions that contain malicious code. If you want to keep using it, but be safe just in case, this issue contains a screenshot showing how to replace the metadata server, including a working alternative by the old contributors now working on the fork called Prism Launcher.
