Are you sure you are a manager for that specific collection? Or that you are a Manager who is able to manage all collections?
If not, then this is the expected endresult.

I just checked its only with newly created Collections. After creating the Collection you cant edit it. In this case, you are manager of the Collection.
I also Updated the Description.

I'm not able to reproduce this in any way.
I created a new manager with the Manage all collections

That user is able to create, edit and delete collections created by that user.
If i assign a user to the custom role and not enable Manage all collections and grant that user Manage rights to a new Collection, that user is able to adjust rights or rename that collection, but isn't allowed to delete it, which is the intended behavior.

Maybe try to update the user's rights, that might help?
Or, there are group policies applied which might prevent that manager from having manage access? Since least privileges are used if set somewhere if I'm correct.

Root Cause Analysis

I investigated this issue and found the bug in the collection creation endpoint at src/api/core/organizations.rs, line 524.

When a Manager without access_all creates a new collection, the code adds a CollectionUser record for them, but with manage=false:

if headers.membership.atype == MembershipType::Manager && !headers.membership.access_all {
    CollectionUser::save(&headers.membership.user_uuid, &collection.uuid, false, false, false, &conn).await?;
    //                                                                                    ^^^^^
    //                                                                              manage = false
}

Later, when the Manager tries to edit that collection via PUT /api/organizations/<org_id>/collections/<col_id>, the ManagerHeaders request guard calls Collection::is_coll_manageable_by_user(), which checks for any of these conditions:

users_collections.manage == true — false (the bug)
users_organizations.access_all == true — false (Manager doesn't have access_all)
users_organizations.atype <= Admin — false (Manager is not Admin/Owner)
Group-level access_all or manage — depends on config

Since none of the conditions are met, the guard fails with "The current user isn't a manager for this collection" and returns 401.

Why it wasn't reproduced by @BlackDex

The test was done with a Manager that had Manage all collections enabled, which sets access_all=true on the membership. In that case, the condition on line 523 (!headers.membership.access_all) prevents the code block from executing at all — and the permission check passes through condition #2 above. The bug only manifests when the Manager does not have access_all.

Fix

The last parameter of CollectionUser::save (manage) should be true instead of false. If a Manager has permission to create a collection, they should logically be able to manage it:

- CollectionUser::save(&headers.membership.user_uuid, &collection.uuid, false, false, false, &conn).await?;
+ CollectionUser::save(&headers.membership.user_uuid, &collection.uuid, false, false, true, &conn).await?;

Nice that AI found something, but a non-access all manager isn't allowed to create collections if I'm not mistaking.

I can try and check again.

I think you are because currently it just checks
github.com/dani-garcia/vaultwarden@c555f7d198/src/db/models/organization.rs (L517)
so it is not checking whether a Manager has the access_all permission.

And github.com/dani-garcia/vaultwarden@c555f7d198/src/api/core/organizations.rs (L523-L525) also does not prevent a manager from creating a collection without access_all either so this should both be adjusted if it's not intended.

Ah, yet a nother situation of not fully validating the API Calls.
The web-vault doesn't allow it, but probably the API does, that should be fixed than.

Ill have to check a bit better regarding the rights though, but i think we currently do not allow non access all managers to create collections. I even recently fixed a security issue because of this.

Ah well, i think i tried that, and was indeed able to do that, but still also able to adjust and delete.

But, as mentioned, ill check again, and see what the correct rights and way should be.

@rafaelfariasbsb commented on GitHub (Feb 26, 2026):

Thanks for the additional context. Based on the discussion, it seems there are two possible approaches here:

A) Allow non-access_all Managers to create collections (current web vault behavior):
The fix would be as proposed in the PR — set manage=true when saving the CollectionUser record, so the creating Manager can manage their own collection.

B) Restrict collection creation to Managers with access_all only:
The fix would be to add a validation check in the creation endpoint to reject requests from Managers without access_all, aligning the API with stricter permission rules.

@BlackDex which approach do you consider correct? I can adjust the PR accordingly.
