CVE intelligence and bounded remediation
CVE-2025-62793 — eLabFTW is an open source electronic lab notebook for research labs
eLabFTW is an open source electronic lab notebook for research labs. The application served uploaded SVG files inline. Because SVG supports active content, an attacker could upload a crafted SVG that executes script when viewed, resulting in stored XSS under the application origin. A victim who opens the SVG URL or any page embedding it could have their session hijacked, data exfiltrated, or actions performed on their behalf. This vulnerability is fixed n 5.3.0.

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.
