The LearnPress WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient escaping on the $custom_profile parameter found in the ~/inc/admin/views/backend-user-profile.php file which allowed attackers with administrative user access to inject arbitrary web scripts, in versions up to and including 4.1.3.1. This affects multi-site installations where unfiltered_html is disabled for administrators, and sites where unfiltered_html is disabled. Please note that this is seperate from CVE-2021-24702.

The LearnPress WordPress plugin before 4.1.3.1 does not properly sanitize or escape various inputs within course settings, which could allow high privilege users to perform Cross-Site Scripting attacks when the unfiltred_html capability is disallowed

The LearnPress plugin before 3.2.6.9 for WordPress allows remote attackers to escalate the privileges of any user to LP Instructor via the accept-to-be-teacher action parameter.

LearnPress Wordpress plugin version prior and including 3.2.6.7 is vulnerable to SQL Injection

be_teacher in class-lp-admin-ajax.php in the LearnPress plugin 3.2.6.5 and earlier for WordPress allows any registered user to assign itself the teacher role via the wp-admin/admin-ajax.php?action=learnpress_be_teacher URI without any additional permission checks. Therefore, any user can change its role to an instructor/teacher and gain access to otherwise restricted data.
