7.1High
CVE-2026-93014
RosarioSIS versions before 12.9 fail to validate the filename request parameter in Users and Students modules, allowing authenticated users to unlink allow-listed files via path traversal. Attackers can use parent-directory sequences to escape upload directories and delete CSS, XML, JSON resources and other users' documents throughout the installation.
What this means for your business
- An attacker can use it remotely, over a network, with an ordinary user login, and without anyone at your company clicking anything.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
