[3] On April 5, 2019, Kim was booked by the police for circulating illegally taken pictures of women in the Jung Joon-young KakaoTalk chatrooms, a mobile chat with fellow celebrities in 2016; a police investigation is ongoing into the Burning Sun scandal.

On April 11, 2019, he admitted to spreading hidden camera photos taken without consent which he had downloaded from the internet.

[4][5] On April 4, 2019, MBC's "Newsdesk" reported that Eddy Kim was one of the members in a group chat where Jung Joon-young shared illicit videos of him having sex with other women without their consent.

[15][16] Mystic Entertainment revealed later that day that Eddy Kim was in fact in the chatroom, but denied that he was involved in the filming or spreading of the footage.

[17] On March 6, 2020, all charges against Eddy Kim were dropped by the Seoul Central District Prosecutors' Office because the singer had only shared a photo he found online (on one occasion), and did not directly film nor distribute the illicit footage of the women.
