CVE intelligence and bounded remediation

CVE-2026-47324 — ProjectsAndPrograms school-management-system security vulnerability

Medium CVSS 5.1

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.

Matched remediation archetype

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
