Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a Missing Authorization vulnerability in the WordPress plugin 'Remove Duplicate Posts' (versions through 1.3.5). The plugin fails to properly enforce capability checks before performing sensitive operations related to post deletion or management, allowing authenticated users with low privileges (or possibly unauthenticated attackers) to exploit incorrectly configured access control security levels and perform actions that should require higher privileges.
