Mitigatie en Workaroundswordt vertaald…
The primary mitigation is to upgrade the Custom Sidebars plugin to a version that addresses this vulnerability. If upgrading is not immediately feasible, consider implementing strict input validation and output encoding on any user-supplied data used in sidebar configurations. Additionally, implement a CSRF protection mechanism, such as using nonce tokens for all critical actions within the plugin. After upgrading, verify the fix by attempting to trigger a sidebar modification through a crafted URL and confirming that the action is blocked.
