Let's say I have this object:

{
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "pending", activity2: "pending" }
}

where the first keys are IDs from a database. I want to be able to change the values of activity1 and activity2 based on an array:

// 'data' is the object mentioned above.
const usersHaveSpecialContentAssigned = [true, false];

Object.values(data).forEach((item, index) => {
    const arrayActivityProgress = Object.values(item as string[]);
    if (usersHaveSpecialContentAssigned[index] === false) {
        arrayActivityProgress.forEach((progress) => {
            progress = 'unassigned';
            console.log(progress);
        });
    }
});

As you can see, my goal is to change the values of activity1 and activity2 if the corresponding value in usersHaveSpecialContentAssigned is false.

The end result based on the example above should look like this:

{
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "unassigned", activity2: "unassigned" }
}

How can I archieve this? My current approach doesn't update the values.

You can write

Object.values(data).forEach((item, index) => {
    if (!usersHaveSpecialContentAssigned[index])
        item.activity1 = item.activity2 = "unassigned";

You of course need to watch for the index not to be out of range.

As you already know what the ids are going to be, I would write it this way.

var initialData = {
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "pending", activity2: "pending" }
};
var permissionsPerUserDataIn = {"b954WYBCC4YbsMM36trawb00xZ32": true, "pby0CAqQ1hTlagIqBTQf6l2Ti9L2": false, "id3": false};

and write your function like this:

function fixData(permissionsPerUser) {

    for (var [id, values] of Object.entries(initialData)) {
       if (permissionsPerUser.hasOwnProperty(id) && !permissionsPerUser[id]) {  
           values.activity1 = 'unassigned';
           values.activity2 = 'unassigned';
           console.log(`${id}: `, values);
       }
    }
}

fixData(permissionsPerUserDataIn);

Doing it this way will give you more granular control over what permissions will get updated and you will not have to worry if a value in the array gets out of sync for whatever reason.
