CD Projekt Red said Cyberpunk 2077 players should use caution when downloading mods and custom saves for the game after community members discovered a save file exploit that could harm your PC. Reportedly there is a bug that allows hackers to hide malicious executables within certain mods.
Eurogamer talked with CDPR, and the developer said the issue is linked to the external DLL files the game uses. DLL stands for Dynamic-link library, which is a library containing data that multiple programs can access and use at the same time.
Cyberpunk 2077 community member PixelRick discovered the issue, and explained that the issue makes non-executable files executable, which could carry out “any locally executed virus.”
“You should be able to trust data file mods to be harmless, and only be skeptical about executables in general,” PixelRick said to Eurogamer. “This vulnerability makes it impossible to really trust any modded data file for this game until [the] patch.”

CDPR thanked the community for flagging the issue and said they are working on a fix, saying, “We advise everyone to refrain from using files obtained from unknown sources. Anyone who plans to use mods or custom saves for Cyberpunk 2077 should use caution until we release the aforementioned fix.” A temporary fix was already made for Cyber Engine Tweaks, a popular modding tool for the game.
Cyberpunk 2077 has been no stranger to bugs and issues since its launch late last year. The backlash regarding the game’s performance on last-gen consoles caused CDPR to offer refunds for the game, which led to Sony delisting the digital version from PlayStation Network.
Last month, CD Projekt Red co-founder Marcin Iwiński apologized on behalf of the company and announced that Cyberpunk 2077’s free next-gen upgrade is set to launch in the second half of 2021.
Despite all this, Cyberpunk 2077 reportedly had the biggest digital game launch of all time. For more, check out our Review Crew discussion on Cyberpunk 2077: One Month Later.
