CVE-2026-29788 (opens in a new tab)How to fix?
Upgrade miraheze/ts-portal to version 30.0.0 or higher.
Overview
miraheze/ts-portal is a Portal for handling and managing the investigation lifecycle for Trust and Safety at the WikiTide Foundation
Affected versions of this package are vulnerable to Unverified Ownership due to the evidence handling in DPAController::store() within app/Http/Controllers/DPAController.php. An attacker can force the deletion of arbitrary users’ data by submitting a DPA report for someone else with an empty evidence field, which the system treats as a genuine self-deletion request.
Workaround
This vulnerability can be mitigated by disabling convertEmptyStringsToNull in the middleware, or by validating evidence in Http/Controllers/DPAController::store() to not be empty.
