CVE intelligence and bounded remediation

CVE-2024-28100 — eLabFTW is an open source electronic lab notebook for research labs

High CVSS 8.9

eLabFTW is an open source electronic lab notebook for research labs. By uploading specially crafted files, a regular user can create a circumstance where a visitor's browser runs arbitrary JavaScript code in the context of the eLabFTW application. This can be triggered by the visitor viewing a list of experiments. Viewing this allows the malicious script to act on behalf of the visitor in any way, including the creation of API keys for persistence, or other options normally available to the user. If the user viewing the page has the sysadmin role in eLabFTW, the script can act as a sysadmin (including system configuration and extensive user management roles). Users are advised to upgrade to at least version 5.0.0. There are no known workarounds for this vulnerability.

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.
