Vulnerabilities in school-management-system software

CERT Polska has received a report about vulnerabilities in ProjectsAndPrograms school-management-system software and participated in coordination of their disclosure.

The vulnerabilityCVE-2026-47324: ProjectsAndPrograms school-management-system is vulnerable to Stored Cross‑Site Scripting (XSS) in multiple attributes of students and teachers objects. An authorized attacker (e.g., a teacher or administrator) can inject malicious JavaScript that is subsequently executed in other users’ browsers. Critically, when chained with CVE‑2025‑11661, which allows unauthenticated access to backend endpoints, this vulnerability can be exploited by a remote attacker without privileges to inject and execute arbitrary JavaScript.

The vulnerabilityCVE-2026-47325: ProjectsAndPrograms school-management-system uses predictable credentials by generating student's and teacher's passwords solely from the user’s date of birth (e.g., 12072000 for 12 July 2000). The application does not require or prompt users to change the password upon first login. This behavior allows attackers to easily guess or derive valid credentials, leading to unauthorized account access.

The maintainers were notified early about these vulnerabilities but did not provide details regarding affected versions. The version corresponding to commit 6b6fae5 was tested and confirmed vulnerable; other versions were not tested and may also be affected.

We thank Jakub Toczyski for the responsible vulnerability report.
