• I agree to follow Nextcloud's Code of Conduct.

Steps to reproduce

1. I have two Nextcloud accounts configured on Android app.
2. I have chosen my camera folder to autoupload on the first account.
3. My camera folder has been sybchronized on both!
4. Additionally some content from one account (no autoupload) infiltrate to the second one. This is big safety issue!

Expected behaviour

Accounts should be separated from each other.

Actual behaviour

Content mixes, depends on switching between two (or potentially more) accounts.

Hi @tsr8:

Couple questions to make it easier to either replicate or troubleshoot this issue:

• Are the accounts on distinct NC servers?
• When you select the second account profile (the one that you do not want getting your camera photos) then go to Settings -> Auto upload does your Camera folder show the cloud symbol solid (blue) or crossed out (empty)?
• Are all camera photos being uploaded to the second account (the wrong one) or just some of them?
• Are all camera photos being uploaded to the first account (the desired one) properly or are some missing?

[tsr8]

• One NC server.

• On the first acount the cloud is blue, on the second it stays grey.

• Nearly all photos are uploaded, some missing but after long time its almoast all on two accounts. I think NC client upload photos to the selected account at the moment.

It certainly shouldn't. And, at least for me, that's not how it behaves.

1. Do you have any auto uploads configured on the second account?
2. Is the destination folder for the auto upload configured for sharing?

[tsr8]

1. No.
2. No. It synchronizes with desktop app.

[tsr8]

It's even worse now: keep uploading files to wrong account despite I have turned it off (cloud icon grayed).

Just realized this is a dup of #11088 - there's a bit more activity over there. Might want to pop over there.

Yes, i have the same issue. Two accounts configured, auto upload (for camera folders) to Server 1 is enabled. Client just uploaded 6GB of my phones photos to Server 2 which DOES NOT HAVE AUTO UPLOAD ENABLED. Lucky i saw it because server 2 auto-deletes files after two weeks. This is not only a security desaster but generally a major bug.

Yeah, just to repeat the other commentators: this bug can lead to major data loss. if you have auto-upload, with delete from source enabled and a short file retention policy on one of the servers it randomly uploads to: boom your stuff is gone.

I experience exactly the same issue. This is a security nightmare!

Closing in favor of consolidating the tracking of root cause analysis and progress in #11088.

Fixed in #12516 (awhile back now; just updating for those not on the other Issue)
