This is due to insufficient input sanitization and output escaping in the FilterCourseTemplate::sections() method at line 98, where the attacker-controlled attribute is inserted into an HTML class attribute via sprintf('', $class_wrapper_form) without esc_attr() escaping. The FilterCourseShortcode::render() handler does not apply shortcode_atts() filtering, so raw user attributes flow directly through do_action('learn-press/filter-courses/layout', $data) into the template. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. ## CVSS-Vektor ``` CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N ``` | Metrik | Wert | Bewertung | |---|---|---| | AV Angriffsvektor | Netzwerk | bad | | AC Komplexität | Gering | bad | | PR Privilegien | Gering | warn | | UI Interaktion | Keine | bad | | S Scope | Verändert | bad | | C Vertraulichkeit | Gering | warn | | I Integrität | Gering | warn | | A Verfügbarkeit | Keine | good | ## Referenzen - - - - --- _Exportiert aus dem [tsecurity.de CVE-Dossier](https://tsecurity.de/cve?cve=CVE-2026-12732) · Datenquellen: EUVD (ENISA), NVD, OSV, CISA KEV, FIRST EPSS, Exploit-DB, BSI BITS_
