CVE-2026-47324 — Stored XSS in Multiple Points in ProjectsAndPrograms school-management-system

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 maintainers were notified early about this vulnerability 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.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.5% (30-day exploitation probability)+6
Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (ProjectsAndPrograms School Management System).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
