CVE-2026-119035 · Severity: info · Published 2026-11-11

A WordPress plugin that generates schema markup for search engines contains a flaw in its JSON-LD output formatting that allows contributors (low-privilege users) to inject malicious scripts. When the Pretty Print option is enabled and a schema property is mapped to a custom field, attackers can craft payloads that execute in visitors' browsers, potentially stealing credentials, defacing content, or spreading malware across the affected site.

## Technical details

The plugin fails to properly encode structured data output when the Pretty Print option is enabled, creating a stored XSS vulnerability. An authenticated attacker with Contributor role or higher can inject malicious JavaScript via custom fields mapped to schema properties; the unescaped payload is then reflected in the JSON-LD output on the site frontend, executing in all visitors' browsers.
