Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The yaffa package (kantorge/yaffa) versions up to and including 2.0.0 is vulnerable to cross-site scripting through the "Add Account Group" function on the account-group page. An attacker can inject malicious JavaScript that runs in the browsers of users who view that page. The source does not list a fixed version, so no fix is listed; the source gives few further details.
