Name of the Vulnerable Software and Affected Versions Lightweight Sidebar Manager plugin for WordPress versions up to, and including, 1.1.4

Description The issue is due to missing or incorrect nonce validation on the metabox save() function, making it possible for unauthenticated attackers to save metabox data via a forged request. This can be achieved if an attacker can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 1.1.4, update to a version that includes the fix for the missing or incorrect nonce validation on the metabox save() function. As a temporary workaround, consider restricting access to the metabox save() function until a patch is available.
