Machine-written summary

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

Vikunja versions before 2.6.0 (Go module code.vikunja.io/api) return assignee user objects from the task assignees endpoint with the email field left unredacted. Any read-only member of a project can see the email addresses of task assignees, though not other account details. Upgrade to version 2.6.0 or later, which blanks the email field.
