Male friend slept at my place, I didn't tell my boyfriend. Dealbreaker?

Anonymous
My boyfriend (21M) is upset because he found out that my male friend (long friendship, also 21M) slept in my apartment while I (20F) was alone, without telling him, because I didn't think that would be an issue.
They don't know each other.
Our relationship is a little over a year.
He trusts me and has never set boundaries for friends of opposite sex, but now thinks that there was no good reason or excuse for not even mentioning my friend’s sleepover.
Is he overreacting?
