info:
  name: WordPress LearnPress < 4.4.1 - Cross-Site Scripting
  author: anirbala98
  severity: high
  description: |
    LearnPress < 4.4.1 does not escape the c_search parameter before reflecting it into the value attribute of the search input on the Course Builder questions page (/course-builder/questions/), allowing attribute-injection reflected XSS against authenticated admins/instructors.
  impact: |
    Attackers can execute arbitrary JavaScript in browsers of logged-in administrators or instructors, potentially leading to session hijacking or privilege escalation.
  remediation: |
    Update the plugin to version 4.4.1 or later.
