description

LearnPress versions before 4.4.7 can render unescaped request data in an HTML attribute on public pages. An unauthenticated attacker may cause script execution in a visitor's browser if the visitor opens a malicious link; the issue applies to sites using a classic, non-block theme.

mitigation

Upgrade LearnPress to version 4.4.7 or later. Until upgrading, move affected sites away from a classic, non-block theme configuration where feasible.

fixed in 4.4.7
