Mitigation Strategies

The immediate mitigation step is to update SPIP to version 4.4.13 or later, which contains the fix for this vulnerability.

The update can be performed using the spip_loader tool (version 6.2.1), a phar script available at https://get.spip.net/.

After updating, it is recommended to review the list of administrators in the backend to identify and correct any unintended privilege promotions that may have occurred before the update.
