moment.js is outdated and has CVEs

BuddyPress uses moment.js 2.15.1, which is quite a few years old (2016) and has two CSVs (CVE-2017-18214, CVE-2022-24785). Both are node.js related, so I do not think this is a security issue. But it might be good to upgrade to at least 2.29.2 anyway, just to be safe.

I agree, thanks a lot for your ticket. I even think WordPress is now including moment.js we might be able to completely remove it! I look at it asap.

I confirm WordPress uses v2.29.4 of moment.js. I don't think we've made custom changes to this library, I just need to check it was already bundled in version 5.4 of WordPress. If so we should use this one and stop including moment.js into the plugin.

This PR simply & softly deprecates bp-moment JS dependency. That being said, as bp-moment is only used by bp-livestamp to live update human dates/time diff on the website, we could simply remove this dependency and save ~ 740 KB (see Consequence would be the people using a WordPress version < 5.0 (a very limited population, see would not enjoy this live updating feature anymore..

@dcavins what's your opinion about this ^^. Should we simply deprecate and remove in 12.0.0, or can we completely remove this dependency right away ?

Let's deprecate and remove in 12, as we normally would. The issues with the old moment.js don't seem worthy of creating an emergency. :)

I'm 100% in favor of letting WP provide the moment library though, as it, like at.js, is no longer actively maintained and will require manual care.

Thanks for the good-looking patch! I'll try it today.

Deprecate bp-moment JS dependency in favor of WP's moment one

Doing so is taking care of using a fresher version of moment.js (v2.29.4).

Props thomaslhotta, dcavins
