CVE-2021-32691
Auto-merging Person Records Compromised
Apollos Apps is an open source platform for launching church-related apps. In Apollos Apps versions prior to 2.20.0, new user registrations are able to access anyone's account by only knowing their basic profile information (name, birthday, gender, etc). This includes all app functionality within the app, as well as any authenticated links to Rock-based webpages (such as giving and events). There is a patch in version 2.20.0. As a workaround, one can patch one's server by overriding the create data source method on the People class.

Auto-merging Person Records Compromised
Impact
New user registrations are able to access anyone's account by only knowing their basic profile information (name, birthday, gender, etc). This includes all app functionality within the app, as well as any authenticated links to Rock-based webpages (such as giving and events).
Patches
We have released a security patch on v2.20.0. The solution was to create a duplicate person and then patch the new person with their profile details.
Workarounds
If you do not wish to upgrade your app to the new version, you can patch your server by overriding the create data source method on the People class.
create = async (profile) => {
const rockUpdateFields = this.mapApollosFieldsToRock(profile);
// auto-merge functionality is compromised
// we are creating a new user and patching them with profile details
const id = await this.post('/People', {
Gender: 0, // required by Rock. Listed first so it can be overridden.
IsSystem: false, // required by rock
});
await this.patch(`/People/${id}`, {
...rockUpdateFields,
});
return id;
};
