CVE-2019-10226 — HTML Injection has been discovered in the v0.19.0 version of the Fat Free CRM product via an authenticated request to the /comments URI

Medium CVSS 5.4

HTML Injection has been discovered in the v0.19.0 version of the Fat Free CRM product via an authenticated request to the /comments URI. NOTE: the vendor disputes the significance of this report because some HTML formatting (such as with an H1 element) is allowed, but there is a XSS protection mechanism.

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.
