Technical details
The plugin incorrectly validates authorization for publishing content, allowing users with only edit capabilities (such as Contributors) to trigger publication through the revision workflow. An authenticated attacker with contributor-level or higher permissions but without explicit publish rights can elevate their privileges to publish unreviewed posts and pages, bypassing the intended approval process. The vulnerability is fixed in version 4.3.1.
