CVE-2026-10077 — yootheme WordPress theme security vulnerability

Medium CVSS 6.8

The yootheme WordPress theme before 5.0.35 does not prevent its bundled front-end framework from treating certain HTML attributes, which are permitted by wp_kses_post(), as markup, allowing users with the Author role to perform Stored Cross-Site Scripting attacks that execute in the browser of any user who views the affected post.

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.
