Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H

Name of the Vulnerable Software and Affected Versions LearnPress plugin for WordPress versions up to 4.3.2.8

Description The plugin allows unauthorized data deletion because the delete question answer() function lacks a capability check. It exposes a wp rest nonce in the public frontend HTML (lpData) to unauthenticated visitors, which serves as the sole security measure for the 'lp-load-ajax' AJAX dispatcher. This allows unauthenticated attackers to delete quiz answer options by sending a crafted POST request.

Recommendations As a temporary workaround, consider disabling the delete question answer() function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
