| Package Name | Ecosystem | Vulnerable Versions | First Patched Version |
|---|---|---|---|
| slixmpp | pip | <= 1.2.3 | 1.2.4 |
| SleekXMPP | pip | <= 1.3.1 | 1.3.2 |
The vulnerability stems from missing origin validation in carbon message handlers. The commit diffs explicitly show both Slixmpp and SleekXMPP added checks comparing msg['from'].bare to the user's JID in these functions. Without this validation, any carbon message (even from external attackers) would be processed as legitimate, enabling impersonation. The CWE-940 mapping confirms this is a source verification flaw.
