Information disclosure in SSB-DB
Impact
What kind of vulnerability is it? Who is impacted?
Servers running SSB-DB 20.0.0 (which is packaged with SSB-Server 16.0.0) must upgrade immediately.
There is no evidence that other SSB apps are vulnerable or that this problem has been exploited in the wild.
The get() method is supposed to only decrypt messages when you explicitly ask it to, but there's a bug where it's decrypting any message that it can. This means that it's returning the decrypted content of private messages, which a malicious peer could use to get access to private data. This only affects peers running SSB-DB@20.0.0 who also have private messages, and is only known to be exploitable if you're also running SSB-OOO (default in SSB-Server), which exposes a thin wrapper around get() to anonymous peers.
Patches
Has the problem been patched? What versions should users upgrade to?
Yes, please upgrade to SSB-DB 20.0.1 (or SSB-Server 16.0.1) immediately.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
You may be able to disable the most obvious attack vector, SSB-OOO, by disabling the plugin, but you should upgrade immediately anyway.
