CVE-2026-50745 — A missing sanitisation vulnerability exists with user input in the stats-video.php script

Medium CVSS 6.1

A missing sanitisation vulnerability exists with user input in the stats-video.php script. The way URLs to this script were constructed did not follow best practices, and the output of the Smarty custom helper function url was neither properly encoded nor sanitised, allowing user‑supplied input to be reflected without escaping.

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.
