Technical details
The POST /v1/groups/members endpoint in HomeBox prior to 0.26.0 fails to validate caller authorization when adding group members—specifically, it does not require the caller to be a group owner, does not request an invitation token, and does not verify target-user consent or notify the target. An authenticated attacker can abuse this to add arbitrary users to groups they control, disclosing PII and creating prerequisites for related inventory-wipe attacks. The flaw is resolved in version 0.26.0.
